Power drill accessory GRAPHITE 55H302 — drill bit/rod, 64 mm length, 10 mm diameter, 58 g, 1 pc

GRAPHITE 55H302 is a single-piece diamond hole cutter designed for electric drills, with a cutting length of 64 mm and a working diameter of 10 mm. Supplied in blister packaging, this 1-piece accessory weighs approximately 58 g and is intended for precise drilling and cutting in hard surfaces. The tool features vacuum-brazed diamond cutting edges and an M14 threaded connection, offering concentrated cutting power that reduces the risk of surface cracking and supports dry operation.

Advantages

The vacuum-brazed diamond rim provides enhanced wear resistance and consistent cutting performance on hard materials. A small, concentrated diamond cutting area minimizes stress on the surrounding surface to lower the chance of chipping or cracking. The M14 thread ensures compatibility with many standard drill adapters and holders, while the single-piece construction improves stability during use. The tool’s dimensions (64 mm length, 10 mm diameter) and modest weight make it suitable for handheld drilling and easy replacement when specific hole sizes are required.

Suitable for

• Drilling precise holes in ceramic tiles and porcelain
• Cutting openings in natural stone and engineered stone
• Punching holes in glass and glazed surfaces (with appropriate caution)
• Creating holes in brick, concrete and asphalt for light-to-medium tasks

How to use

Secure the hole cutter in a drill with an M14 adapter or holder that accepts M14-threaded accessories. Mark the drilling point on the work surface and start at low speed to establish a stable position, then increase speed as appropriate for the material. Apply light, steady pressure and avoid lateral forces; allow the diamond edge to cut without forcing. For glass and delicate tiles, consider using a guide or backing to reduce vibration and prevent cracking. After cutting, withdraw the tool slowly and inspect the hole for clean edges.

Usage recommendations

Use personal protective equipment including eye protection and gloves. For best results on large or thick materials, perform progressive cutting and consider intermittent pauses to prevent overheating. Test on a scrap piece where possible to confirm speed and feed pressure for the specific material.
