Frequently Asked Questions
What does the LHW/A do that a standard angle grinder can’t?
The long-neck design reaches tight inside corners, narrow seams, and confined spaces that a standard 4″ angle grinder physically can’t access. The 50mm (2″) disc is small enough to work in spots where a full-size grinder would damage surrounding material or simply not fit.
What is a center bore disc mount?
The LHW/A uses a center bore disc system: the disc has a hole through the middle (10mm bore) that drops over a threaded spindle on the tool. A nut threads down on top to clamp the disc flat against the tool’s face the same principle as a full-size angle grinder, just scaled to 50mm. This geometry is what makes the LHW/A a grinder/cutter rather than a rotary tool: the disc spins flat, like a miniature saw blade or sanding pad, and handles lateral force well.
What’s the difference between the LHW/A and the LWB/A?
Both are 10.8V cordless long-neck tools on the same MICROMOT battery platform, but they mount different accessories and do different jobs:
- LHW/A (this tool) 50mm disc mount (center bore + nut). Clamps a flat disc between two flanges. Spins like a miniature angle grinder. Used for cutting, grinding, sanding, and shaping. The go-to for stone fabricators doing small cuts, grinding seams, and sanding tight inside corners.
- LWB/A collet system. Grips a shank (bit, burr, or cutter) from all sides. Spins like a drill. Used for drilling, milling, carving, and polishing. Better suited for restorers, jewelers, model makers, and detail/inlay work in stone.
For fabricators, the LHW/A is the higher-volume SKU. The LWB/A is the precision companion for detail work.
What discs are compatible with the LHW/A?
Any 50mm (2″) disc with a 10mm center bore: cut-off wheels, grinding discs, flap discs, sanding pads, diamond cutting discs, and polishing felts. Items labeled for the LHW/E share the same disc interface and are fully compatible. See the Compatible Accessories section above for specific recommendations.
Should I buy a spare battery?
Yes especially for production use. Proxxon rates the 2.5Ah battery at ~30 minutes at max power. For fabricators hitting it hard, a spare battery keeps you running without downtime. The Proxxon Li/A2 10.8V 2.5Ah battery is compatible with all MICROMOT cordless tools including the LHW/A and LWB/A.
Does this tool work on stone?
Yes it’s the tool fabricators reach for. With the right disc (diamond cutting, diamond flap, or grinding), the LHW/A handles small cuts in tile and stone, grinding seams, and sanding tight inside corners. Pair it with DiStar diamond accessories for best results on hard stone and porcelain.
