What it does

Shaped to connect a Sentro knitting machine to a power drill
Built for a 3/8in drive bit, so check your bit size before you order
Thicker outer wall than the original adapter version
Lets you power your knitting machine with a drill instead of your hand
Made to order in the USA after you place your order

Why turn a knitting machine crank by hand when a drill can do the work? This adapter connects your Sentro knitting machine to a power drill, so you can spin the machine with the drill instead of your arm.

This is the v2 version of the adapter, made for a 3/8in drive bit. It has a thicker outer wall than the original design. The shape fits onto the drive bit and links up to your Sentro knitting machine.

Check that your drill uses a 3/8in drive bit before you order, since this version is built for that size only. It is made to order in the USA once you place your order.
