When you drill a tiny hole, you work with a tiny drill. Using a drill press or a milling machine is tricky business. You can’t get good feel of your peck with a giant machine and a tiny weensy drill bit. You’re just asking for broken bits with each peck. Pecking without a micro drill adapter is just wrong. Don’t do it. Here’s why.
Feel the Peck
When you use your drill press on a regular basis, you get a feel for the machine. Almost instinctively you sense every part of the entire peck cycle. The signals at your fingers transmit to the brain without you thinking. You’re just conscious of keeping chips clear.
It’s not the same when that drill press is outfitted with a little bitty bit. You miss out on tactile sensation. So, adapt the mill or press for fingertip control. It’s easier not hard. Furthermore, it’s not expensive. You got no excuse. It doesn’t require expensive tooling. Just add on a micro drill adapter.
Now you can feel the bit and drill effortlessly. Swap broken bits for an adapter and experience every sensation in every peck cycle.
Modify your press or mill with the micro drill adapter and take control of every peck. Simply insert the small device in the chuck (it works with keyed and keyless chucks) and then mount it on your drill or press. Take control of the bit as the spindle is rotating. It’s easy. Grab the adapter ring and begin the first peck cycle. While the spindle rotates, the adapter gives you control of the bit. Get an even faster setup if you If you really want to be slick, put your bit in the micro drill adapter before you place the adapter in the chuck. How’s that for fast setup?
Also Known As an Accufeed
Most any CNC supply shop sells these adapters. They are also called accufeeds. Like soda and pop are the same drink, accufeed is just just the same tool going around and using a different name.
Buy your micro drill adapter from The Tool Store if you want American-made quality. You’ll get double shielded bearings and a hardened pin design for extra durability. Don’t be wrong. Always make your small holes with a small bit and an adapter that restores fingertip control.

Wouldn’t it be great if your large mill, lathe, or jig borer could be controlled like a hand tool? CNC amps up machining to an awesome level. But, all that power, speed and automatic tool changing no longer makes the tool feel like an extension of your body. Admit it, there are times when you would like a bit of fingertip control. Like if you need to drill small holes. That’s when you really want fingertip control. Fortunately, for those times you can still get the feel of a hand tool with a drill press. A micro drill adapter gives you hand sensitive control of your drill press.
Controlling the Peck Cycle
As you already know, holes are drilled using a peck cycle. Your drill bit is like a chicken or pigeon pecking at grain. Except your drill bit is pecking at wood, metal, or plastic. Peck drilling stops swarf build up. You must peck if the depth of the hole is more than three times the width. When pecking, the drill bit goes in less than 5 times the diameter of the hole and then comes partially back out. Then you do it again. And again. And again till you reach the depth you need. The bit never leaves the work completely. It retracts the drill only slightly. This style of peck drilling is faster but it only works on long holes. It’s easy to overheat break the drill bit. And it’s easy to break the bit when drilling really small holes. The smaller the hole, the smaller the bit. The smaller the bit the more control you need.
If you’ve got a very large and extremely powerful machine but you need a little hole, you’ve got a problem. If you used a hand tool, you would automatically have that tactile sense of the peck. But your big drill press wasn’t made for that kind of operation. However, if you modify your press with a micro drill adapter you can get that kind of control. Install quickly on your drill press and suddenly you have fingertip control. You peck confidently, even when you peck at a small hole. Peck gently with finger pressure then release. It auto returns to the top of the cycle.
Get it at The Tool Company
Make sure you get the right micro drill adapter. Get it at The Tool Company. The hardened pin design avoids problems with the tool-holding collet. Doesn’t matter if your chuck is keyed or not. That’s because the “O” tapper fits both. The bearings are double-shielded, so it lasts. But don’t worry about tool life, you get a 5 year warranty. You won’t find that elsewhere.
Like everything at The Tool Company, it’s made in the USA. It’s made for The Tool Company by Sierra American Multi-Systems and they understand control. For a small hole, you need control. If you need control, install a micro drill adapter. And buy a micro drill adapter from The Tool Company.
It’s just a fact of life. Some jobs in the CNC shop require very small holes. The only way you can get a small hole is with a really small bit. Problem is, those really small bits mean huge problems for big machines. You need a solution and you need precision. What you need is a micro drill adapter or an accu-feed.
Small holes go hand-in-hand with precision jobs. You may need to make a small hole if you are making jewelry or watchmaking. If your job requires scroll work, you are going to need to make small holes. Machining for the electronics industry requires very, very small holes. The medical industry has many applications that require small holes. Sometimes the machinist working in the hobby workshop has a need for small holes. It feels like small holes are everywhere. That’s because they are everywhere.
From the machinist’s point of view, small holes are a problem because you need a small bit to make a small hole. Those bits with a small diameter are notoriously fragile. The mills, lathes, and drill presses in a CNC shop are not small. But you must harness those big machines to turn your very small bit to make that tiny hole. You can’t win for losing. Well, okay, it might not be that bad but you will certainly break many bits in the process. Surely there is a better way.
You Must Have Sensitivity
When you mount a small bit in a huge drill press and pull the handle down, you have no sense of the peck. There is no tactile sense from the bit.
That drill press handle can’t give you the input you need to determine the level of pressure you apply with each peck. This is a problem because very small bits are not built for pressure. They just can’t take it. Those small bits will snap and break when drilling that small hole you need. Very frustrating!
What you need is something that you can attach before the tool-holding collet. You need something that will give you fingertip control. You know, that special control you get from the sensitivity at the tips of your fingers. Imagine if you could peck as if the drill bit was an extension of your hand.
This is exactly the precision and control you get if you drill with a micro drill adapter or accu-feed.
Precision, controlled drilling isn’t a pipe dream if you attach a micro drill adapter.
The micro drill adapter (also known as an accu-feed) allows you to get fingertip sensitivity with a very small bit even if you use a very big machine.
You install a micro drill adapter between the chuck and the collet. Lower the bit and start your peck cycle with sensitivity. You get virtual fingertip control. Know you an feel the exact amount of pressure you are applying. Because you can feel the bit you snap fewer bits. It’s so much easier to drill the tiniest o holes with ease and precision if you can feel what you are doing.
You can drill a small hole with ease if you use a micro drill adapter. Drill small holes with huge machines without snapping bits. Just add a micro drill adapter to your drill press.
The Tool Company offers an accu-feed that is a micro drill adapter made with double shielded bearings for smooth operation. It is a tough micro drill adapter that delivers on sensitivity. You get a tool that is hardened and precision ground for accuracy. The unique, hardened pin drive design won’t let you down by weakening0 or expanding like inferior “c” clip styles.
Like every tool at The Tool Company, this accu-feed is made in the USA.

Homer Simpson can be relied upon to eat any doughnut around and leave the Springfield Nuclear Power Plant in chaos at the end of his shift. But Homer knows his tools and he knows quality micro drill adapters when he sees them. He recognizes tools that are “D’oh” proof. Here’s what he would say.
Micro Drilling Is Different
The physics of machining is more precise the smaller you go in scale. Even Homer knows micromachining isn’t just drilling in miniature, it is more sensitive
To micromachine effectively you need to use high speed spindles with low run out. You also need rigidity. If it isn’t rigid the contours will change as the force changes. That means you don’t get the results that you set up to achieve. That’s a waste of machine time, human labor, and material. D’oh!
You need more than just the right machine and drill. That’s because toolholding technology for micro drills is as important to the operation as the machine tool. You need a high precision collet that has been hand clamped to the spindle to insure accuracy. Automatic toolchangers are great, but they can be inaccurate. Small inaccuracies aren’t small in micromachining.
Even Homer knows this!
Pay Attention to the Details
Homer may ignore his wife and children but he knows successful microdrilling requires attention to detail. That’s why he works at a nuclear power plant and not a CNC shop.
The first detail is the drill material itself. Use only the highest quality drills with the shortest cutting flutes possible to do the job. High speed steel is preferred over carbide unless the work piece material calls for carbide.
Secondly speeds and feeds are critical. The feed rate must be controlled and the drill can’t be pulled into the work piece. If your drill gets pulled in you will probably break your drill. Use an RMP under 3000. Running at a high RPM means you must have a faster feed rate just to counteract work hardening. High RPMs can decrease the life of the cutting edges on your drill.
