Power drill accessory GRAPHITE 55H300 — drill bit 64 mm length, 6 mm diameter, 1 pc

GRAPHITE 55H300 is a single-piece diamond hole cutter supplied in blister packaging. The tool features a 64 mm overall length and a 6 mm diameter cutting head, designed for use with power drills that accept 6 mm shanks. Vacuum-brazed diamond cutting edge concentrates cutting force in a small contact area, enabling precise holes in hard surfaces while reducing the risk of cracking. The accessory is intended for dry cutting and is sold as one piece per pack.

Advantages

The vacuum-brazed diamond rim provides enhanced wear resistance and maintains cutting performance over repeated use. The compact 6 mm diameter and 64 mm length allow access to narrow drilling positions and provide stable guidance during drilling. Designed for dry operation, the cutter eliminates the need for continuous coolant in many tiling and masonry tasks. The single-piece construction reduces the risk of component loosening and simplifies mounting in compatible drill chucks.

Suitable for

• Cutting precise small-diameter holes in ceramic tiles and porcelain stoneware
• Drilling through natural stone and engineered stone surfaces
• Creating openings in glass and glazed surfaces where controlled cutting is required
• Punching holes in brick, concrete and asphalt for light anchors or service passages

Key specifications

• Cutting diameter: 6 mm
• Overall length: 64 mm
• Cutting edge: vacuum-brazed diamond
• Intended operation: dry cutting
• Construction: single-piece design
• Weight: approximately 52 g

How to use

Fit the 6 mm shank securely into the drill chuck and tighten according to the drill manufacturer's instructions. Mark the drilling position and start at low speed to establish a precise contact point; increase speed gradually while applying light, steady pressure. Maintain a perpendicular angle to the work surface for accurate hole geometry. For materials that build up dust, periodically withdraw the cutter to clear debris and reduce heat. Observe the drill's recommended RPM range for diamond cutting accessories to avoid excessive wear.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, dust mask and gloves. For fragile or glazed surfaces, consider using a guide or tape to prevent slipping at the start. Although designed for dry cutting, short pauses to clear debris will help prolong tool life; avoid prolonged continuous high-speed use to reduce thermal stress on the diamond bond.
