At 400,000rpm the customer experiences complete cutting control in any material as well as no heat and no vibration. This ultra high speed engraver will allow you to engrave on various surfaces with extreme ease. The POWERCRAFTER is a small light weight Air Turbine Tool that is shaped like a large pen. The size, shape, and rotation speed of the POWERCRAFTER dramatically increases the users comfort and control of the tool. It has a friction grip collet assembly that allows for quick-release and reinsertion of the cutters (Shaft size 1/16th only). The tool also incorporates a quick disconnect fitting at the rear of the tool so it can be easily disconnected from the air supply for ease of lubrication and storage. Other tools only have a hose barb fitting which has to be pried off to lubricate the tool. This tool is a must have for anyone doing fine detailed work.
