Proxxon LWB/A Cordless Long Neck Rotary Tool | 10.8V Precision Drilling, Milling & Polishing

The Proxxon LWB/A is a cordless long-neck rotary tool built for precision work in tight spaces — drilling, milling, engraving, sanding, and polishing where a standard tool simply won't fit. Powered by Proxxon's 10.8V MICROMOT platform, it delivers 30+ minutes of runtime with variable speed from 5,000–16,000 RPM and a MICROMOT collet system that accepts bits from 0.04" to 0.13" (1–3.2mm).

LWB/A vs LHW/A — Which Do You Need?

The LWB/A uses a MICROMOT collet system for drilling bits, milling cutters, and engraving tools. The LHW/A uses a center-bore disc mount for 50mm cutting and grinding discs. For tile fabricators doing precision cutouts and detail work, the LWB/A is the right choice. For straight cuts and edge grinding, choose the LHW/A.
