## Long description

GRAPHITE 55H301 diamond hole cutter, single blister pack, is a compact rotary tool accessory with an 8 mm cutting diameter and 64 mm overall length. Weighing 56 g, this hole cutter is vacuum-brazed with diamond grit on the cutting crown and is intended for precise cutting of hard surfaces such as natural stone, porcelain stoneware, ceramic tiles, glass, asphalt, brick and concrete. The cutter is fitted for use with an M14 thread adaptor and is compatible with drill chucks that accept an 8 mm shank; it is suitable for dry cutting applications where small, accurate holes are required for installations and repairs.
Advantages
The diamond cutting edge concentrates abrasive action in a narrow ring, enabling clean, accurate openings while reducing the risk of cracking or chipping on brittle surfaces. Vacuum brazing secures the diamond particles to the tool body, improving wear resistance and extending usable life under typical dry cutting conditions. Its compact dimensions and 8 mm diameter make it convenient for precise tasks and installations where controlled hole size and straight cuts are needed. The single blister pack keeps the tool protected and identifiable prior to use.
Suitable for
 Cutting clean holes in ceramic and porcelain tiles for plumbing and electrical installations
 Drilling small-diameter openings in natural stone and stoneware
 Making pilot or finishing holes in concrete, brick and asphalt for anchors and conduits
 Creating precise holes in glass for specialized mounting or decorative work (with appropriate technique)
Key specifications
 Cutting diameter: 8 mm
 Overall length: 64 mm
 Weight: 56 g
 Thread/adapter: M14 mounting
 Cutting material: vacuum-brazed diamond grit on crown
 Suitable cutting mode: dry cutting
 Compatible shank/chuck: 8 mm shank holders and standard drill chucks
How to use
Install the hole cutter onto a drill or rotary tool using the M14 adapter or an appropriate chuck that accepts the 8 mm shank. Secure the tool in the chuck and ensure it is tightened before operation. Mark the drilling position on the work surface and, when possible, score or start with a pilot mark to keep the cutter centered. Operate the drill at moderate speed and apply steady, light pressure—avoid heavy force that could overheat or damage the material. For glass and very brittle materials, support the workpiece and consider using a backing material to reduce chipping. After cutting, clean the hole of dust and debris and inspect the edge for required finishing.
Usage recommendations
Use steady air cooling by allowing brief pauses between cutting intervals to prevent overheating when dry cutting. Wear appropriate personal protective equipment including eye protection, gloves and a dust mask. For extended life of the diamond crown, avoid excessive lateral force and maintain moderate drilling speed suited to the work material.
