Nakanishi NSK Mini-Luster ML-8 Attachment Handpiece LS51307

The Nakanishi NSK Mini-Luster ML-8 Attachment Handpiece (LS51307) is a reciprocating polishing handpiece designed for use with the EMax Evolution and ROTUS micromotor systems. Its pencil-style grip and fixed 0.8mm stroke make it exceptionally well suited for polishing narrow grooves, fine details, and hard-to-reach areas quickly and with minimal effort. Unlike a hammer handpiece, this tool produces very little impact force — its function is precision polishing, not percussion.

You can use any tool that will fit in the 3.5mm round tool hole. The factory states that the tool hole diameter is 0.13" which is equivalent to 1/8", since many tools are available in 1/8".  But the actual tool hold diameter is 3.5mm. Tools are held down with a single 1.5mm hex nut.  A 1.5mm hex key is supplied.

Includes NSKGrindstone Holder with 3mm diameter shank. Allows for use of flat ceramic files up to 1.2mm thick by 6mm wide held in place by single 1.5mm hex screw

Use it with ceramic polishing sticks or attach Glardon-Vallorbe miniature files via the included grindstone holder for pre-polishing applications. The lightweight, compact body and minimal vibration design reduce hand fatigue during long, continuous work sessions.

Note: This is not a hammer handpiece. Impact strength in the stroke is minimal — it is intended for polishing use only.
