Frequently Asked Questions
What is a long neck rotary tool used for?
Precision drilling, milling, sanding, and polishing in tight or hard-to-reach areas — corners, inside profiles, and confined spaces where a standard tool body won't fit.
How long does the battery last?
Up to approximately 30 minutes at full power. For production use, a spare Proxxon Li/A2 2.5Ah battery keeps you running without downtime.
Is it suitable for tile and stone work?
Yes — ideal for tile trimming, edge work, and detail finishing. Pair with the Distar Water Guard Kit for wet cutting to control silica dust.
What is a collet, and how does it work?
A collet is a slotted metal sleeve that grips a tool's shank from all sides when a nut is tightened. The LWB/A ships with 6 MICROMOT hardened steel collets covering 1.0, 1.5, 2.0, 2.4, 3.0, and 3.2mm shank diameters — compatible with standard MICROMOT accessories including drill bits, router bits, milling cutters, burrs, and polishing bobs.
What's the difference between the LWB/A and the LHW/A?
Both are 10.8V cordless long-neck tools on the same MICROMOT battery platform, but they mount different accessories and do different jobs:
- LWB/A (this tool) — collet system. Grips a shank from all sides. Used for drilling, milling, carving, polishing, and detail work. Speed: 5,000–16,000 RPM.
- LHW/A — 50mm disc mount. Clamps a flat disc between two flanges like a miniature angle grinder. Used for cutting, grinding, sanding, and shaping.
If you're a stone fabricator, the LHW/A is the higher-volume cutting tool. The LWB/A is the precision and detail companion. Full comparison: Proxxon LWB/A vs LHW/A →
Should I buy a spare battery?
Yes — especially for production use. The Proxxon Li/A2 10.8V 2.5Ah battery is compatible with all MICROMOT cordless tools including the LWB/A and LHW/A.
What accessories are compatible with the LWB/A?
Any accessory with a shank diameter matching one of the 6 included collets (1.0–3.2mm): drill bits, router bits, milling cutters, mounted grinding points, burrs, polishing bobs, and carving bits. Standard MICROMOT accessories from Proxxon are a direct fit.
