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.
