Proxxon Precision Tools for Tile, Stone, and Detail Work

The back corner of a shower niche is not reachable with a 4 1/2" grinder. It also can't cut 3 mm from porcelain tile already installed against a pipe. Here’s the solution: Proxxon tools are designed for jobs like this. They run 50 mm discs, slim gear heads, and motors that operate with one hand, letting you cut, drill, grind, and polish where full-size equipment cannot fit.

Our collection includes corded and Proxxon cordless tools, plus the diamond blades, polishing pads, and abrasives made for them. Tile setters use them for notches and outlet cutouts. Stone fabricators use Proxxon tools to edge marble and granite. Metalworkers use them to deburr small parts and strip rust.

Proxxon Long Neck Angle Grinders: LHW/E and LHW/A

The corded LHW/E is 290 mm (11-13/32") long and weighs 550 g (1.2 lb). Its slim neck fits into grinders without getting stuck in the grinders' slots. A 100W DC motor on 110-120V delivers variable speeds from 3,300 to 13,000 RPM. Use it sparingly on polished stone and glass to prevent heat buildup. Use on steel for stock removal at high settings. It includes a 60-grit aluminum oxide grinding disc, a 100-grit flap disc, and a cut-off wheel.

The LHW/A is the cordless version. Powered by the 10.8V Li/A2 battery at 5,000-16,000 RPM, it measures 320 mm and weighs about 800 g, including the battery. Proxxon rates it for a minimum of 30 minutes at full power.

Both grinders use a 50 mm disc (10 mm (13/32") bore). There is a set of blades that are used for both tools. Use the BHW/C for longer sessions. Go for LHW/A when the closest outlet is 2 floors away or when you don't want a cord on wet tile.

Cordless Proxxon Milling and Drilling Tools

The LWB/A long-neck angle milling/drilling unit uses collets rather than a disc arbor. It comes with six MICROMOT hardened steel collets, sized 1.0, 1.5, 2.0, 2.4, 3.0, and 3.2 mm. This allows you to use diamond bits, carbide cutters, and mounted points at right angles. Proxxon designed it with tile in mind. You can use a diamond bit to cut through porcelain and follow a cut around a toilet flange or a square outlet box.

Speed is variable from 5,000 to 16,000 RPM. The gears are housed in the die-cast aluminum head, which provides stability of the bit during use at an angle.

Already have a Proxxon rotary tool for bench work in the MICROMOT range? The LWB/A is identical to the Standard, but with a 90-degree collet rotation on a 320 mm LWB body. When drilling pilot holes in glass mosaic or porcelain, use with the PROXXON Diamond Drill Bits (1/32" and 3/64").

Proxxon WP/E Angle Polisher and Polishing Sets

It has a 100W motor that operates between 800 and 2,500 RPM and features a hook-and-loop backing pad. This low gear ratio is important. If you spin on marble too quickly, you will burn it. If you spin too quickly on clear coat, you melt it. Polish granite edges after cutting, buff chrome and brass fixtures, and remove etch marks from marble vanity with the WP/E.

Diamond-coated sanding and polishing pads are packaged in 50, 100, 200 and 400 grit, 3 per pack. Use a stone edge and work through them in order; do not skip grits. After 400, turn to the silicon carbide discs in 400 grit and 1000 grit (12 per pack). Use the conical polishing sponges in soft, medium or hard, a lambswool disc, or medium-hard polishing felt. The WP/E & WP/A Professional Finish Grinding and Polishing Set contains grinding & polishing media for the corded and cordless polisher in one package.

Proxxon Cutting Discs, Diamond Blades and Flap Discs

All discs in this section are 50 mm with a 10 mm bore and designed to fit Proxxon power tools that use that arbor.

For porcelain and ceramic: the 0.8 mm Porcelain Cutting Blade leaves a thin kerf and minimal chipping at edges coated with glazes. The Porcelain Turbo Cutting Blade is faster and makes a slightly rougher cut. Use a 100-grit diamond pad to plan to clean it. The Diamond Cutting & Roughing Disc can be used for both cutting and shaping, making it convenient to round a notch. The Tungsten Carbide Rasp & Cutting Disc is perfect for wood, plastic, and fiberglass.

For metal, keep a 5-pack of cut-off wheels, plus flap discs in 100 and 240 grit. The 60-grit silicon carbide grinding disc can clean weld spatter and heavy rust quickly.

Frequently Asked Questions

What is a Proxxon long neck angle grinder used for?

Grinding, cutting, deburring, and finishing in enclosed areas. Typical tasks are notching tile, removing paint or rust from small parts, cutting small metal components, and sharpening tools. Proxxon is considered an electric version of pneumatic grinders.

Can the Proxxon LHW/E cut porcelain tile?

Yes. Fit the 0.8 mm Porcelain Cutting Blade or Porcelain Turbo Cutting Blade. Take several shallow passes when using thick tile - use a slower blade speed and let the blade do the work. Wear a respirator. Dry-cutting porcelain releases crystalline silica dust.

Do Proxxon cutting discs work on other mini grinders?

They can be used on any tool that accepts 50 mm (2") discs with a 10 mm (13/32") arbor, with a maximum disc top speed of no more than the maximum RPM printed on the disc. They won't fit a standard 4-1/2" grinder, which uses a 22 mm (7/8") arbor.

Is the cordless LHW/A as powerful as the corded LHW/E?

Proxxon rates the LHW/A performance to be similar to its corded models. The LHW/A tops out higher at 16,000 RPM versus 13,000. The LHW/E, on the other hand, has a lower starting speed of 3,300 RPM, and runtime is approximately 30 minutes per charge at full power. If you're working at a bench for a long period of time, then use corded. For mobility, go cordless and keep a second battery charged.

What comes in the Proxxon L-BOXX combo set?

The L-BOXX combo set (P/N 39900) combines the LHW/A cordless long neck angle grinder with the LWB/A cordless long neck milling/drilling unit. It also includes two 10.8V Li/A2 lithium-ion batteries and an LG/A2 rapid charger that charges a battery in about 1 hour. All fit in a flat L-BOXX and have space for accessories with a molded insert.
