Description
The bit does not sit in a chuck. It sits in a 3.175 mm collet with a brass nose, and a collet grips a shank all the way round instead of on three jaws. That is the whole reason this machine exists. At 0.3 mm the difference between a collet and a chuck is whether the bit walks before it bites.

3.175 mm is the eighth-inch shank. PCB micro bits, tungsten carbide engraving bits and most rotary-tool burrs are ground to it. If your bits have a colored plastic collar on them, they are 3.175 and they will go in. To hold a plain 2 mm twist drill by its own shank, our chuck version takes 0.3 to 4 mm.

The base is the part to look at
Two long slots through it, and a ring of small holes around a hole in the center. That is a mounting pattern, so you can bolt a vise down instead of holding the work with your fingers.

How it works
- Belt drive, round green belt, stepped pulleys. Move the belt to another step and the whole speed band shifts. Five seconds, no tools.
- Lever feed, two arms, brass ball handles. You pull it down and let it back up. For depth set by the hundredth, see the micrometer machine.
- The speed control lives on the power adapter, a dial marked POWER CONTROL. There is no switch on the machine itself.
- 100 to 240 V. Wall-outlet voltage is a non-issue on 120 V American and 230 V Australian supply. No converter.
- Ordering from Australia or New Zealand? We send an Australian and New Zealand pin adapter with your machine, free, in its own small parcel. It takes both flat US pins and round European ones, so the plug goes into your wall. If it still does not, tell us and we post you the correct one free, or refund you in full with the return postage on us.

What the owners say
Five ratings, 4.8 average, every one a verified purchase. One owner: it works very well and precisely with a 0.3 mm drill, no trouble. If your machine arrives without its rubber feet, write to us and we send you a set.
What it is for
Wood, plastic, resin, composite panel, PCB, brass, copper, aluminum. Not for hardened steel - and it is a drill, not a mill.
Delivery

30-day returns from the day it arrives. Return postage is yours, the price of the item comes back in full.
Shipping and returns
Free tracked shipping on every order to the United States, Australia, New Zealand and Canada, with no minimum. A few items ship to a shorter list of countries, and their page says so.
Orders leave within 2 business days. The delivery time for your country is shown under the price of each item. In the United States the Mini Drill Press, the lathes, the XYZ and XYZR micrometer stages and many of the tools ship from US warehouses and arrive in about a week or less. Items shipped from overseas take one to two weeks, a few larger ones two to four. You get a tracking number by email as soon as the parcel is scanned.
30-day returns from the day it arrives, unused and in its packaging. If it arrived damaged or faulty, we pay the return label. If you simply changed your mind, you pay the return postage and get the full price of the item back. Email support@arvonelle.com before sending anything back.
Before you order
Do I pay tax or duty? In the United States, sales tax is added at checkout where your state charges it, and the total you see is what you pay. For Australia and New Zealand nothing is added at checkout. If a carrier ever asks you for a fee on one of our parcels, don't pay it: email us first and we sort it out.
What if a part breaks? For twelve months, tell us which part and we post a new one free. No return needed.
Can I cancel? Yes, within 24 hours of ordering, no questions asked.
