Drill bit AWTools AW47254 — power drill accessory, weight 31 g

AWTools AW47254 drill bit is a power drill accessory made of steel with a golden finish and a vacuum-brazed diamond grit cutting edge. Weighing 31 g, the bit is engineered for precise hole making in hard ceramic materials. A side hole assists efficient material removal, and the design allows dry or wet drilling in stoneware, ceramic, marble, porcelain and hard tiles. The bit is intended as a replacement or spare for routine repair, construction and DIY tasks where a lightweight, high-precision drill accessory is required.

Advantages

The vacuum-brazed diamond grit on the cutting edge provides high precision and smooth cutting performance while the steel body with golden finish increases surface durability and corrosion resistance. The side hole improves debris evacuation to reduce clogging and overheating during drilling. The bit’s compact weight and universal shank profile make it compatible with corded and cordless drills when used with appropriate coolant, enabling both dry and wet drilling modes.

Suitable for

• Drilling holes in ceramic and porcelain tiles
• Cutting through marble and stoneware for countertops and fixtures
• Creating water inlet and drain openings in tiled surfaces
• Installing light points and small plumbing penetrations
• General repair, renovation and DIY tile work

Key specifications

• Material: steel body with golden surface finish
• Cutting edge: vacuum-brazed diamond grit
• Weight: 31 g
• Suitable materials: stoneware, ceramic, marble, porcelain, hard tiles
• Drilling methods: dry or wet drilling with appropriate coolant

How to use

Fit the drill bit into the drill chuck securely and set the drill to an appropriate speed for hard ceramic materials. When possible use a coolant or water feed for wet drilling to extend bit life and reduce dust. Start drilling at low speed to create a guide point, then increase speed and apply steady, moderate pressure. Use the side hole and periodic retraction to help clear debris and prevent clogging. For deep or precise holes, keep the drill perpendicular to the surface and pause periodically to let the bit cool.

Usage recommendations

Use eye and dust protection, and ensure the workpiece is secured. For porcelain and high-density marble, prefer wet drilling with continuous coolant; for small diameter holes in thin tiles, reduce pressure to avoid cracking. Inspect the bit before use and replace when the cutting edge shows excessive wear.
