Drill bit set AWTools AW47294 — accessory for power drills, model AW47294

AWTools AW47294 is a set of steel drill bits with a golden finish, designed as an accessory for power drills and angle grinders. The cutting edges are coated with vacuum-brazed diamond grit to deliver precise, smooth cutting performance. A side hole on the bits improves removal of drilled material, and the geometry is intended for dry or wet drilling in hard ceramic materials such as stoneware, ceramic, marble, porcelain and hard tiles. The set is suitable as a replacement or extension to an existing drill toolkit for workshop, construction and DIY tasks.

Advantages

The vacuum-brazed diamond grit on the cutting edge provides high precision and extended wear resistance compared with uncoated carbide tips. The steel body with a golden surface finish resists corrosion and enables stable handling during operation. The side hole facilitates faster evacuation of dust and debris, helping to maintain cutting progress and reduce clogging when drilling deep holes. Compatibility with dry and wet drilling methods and suitability for use with an angle grinder (with appropriate coolant) make the set versatile for multiple installation and repair tasks.

Suitable for

• Drilling holes in stone countertops for water inlets and drains
• Creating openings for electrical light points and fixture installtions in tiles
• Cutting holes in ceramic, porcelain, marble and hard tiles for plumbing and HVAC passes
• General workshop and construction drilling tasks on hard brittle materials

Key specifications

• Material: steel with golden surface finish
• Cutting edge: vacuum-brazed diamond grit coating
• Drilling mode: suitable for dry and wet drilling
• Compatible materials: stoneware, ceramic, marble, porcelain, hard tiles
• Feature: side hole for efficient material removal
• Recommended tools: power drill and angle grinder (angle grinder use requires appropriate coolant)

How to use

Select the appropriate bit size from the set and secure it in the chuck of a power drill or the arbor of an angle grinder, ensuring the tool is switched off and unplugged during installation. For angle grinder use, fit the correct adapter and provide continuous coolant to prevent overheating. Start drilling at low speed to create a guide point, then increase speed gradually while applying steady, moderate pressure. Use wet drilling when possible for improved dust suppression and cooling; when dry drilling, pause regularly to allow the bit to cool and to clear debris through the side hole. After completing the hole, clean the bit and the work surface of residual dust and abrasive particles.

Usage recommendations

Use personal protective equipment including safety goggles, gloves and a dust mask. When drilling tiles or natural stone, secure the workpiece and test on a scrap piece to confirm feed rate and coolant flow. For angle grinder applications always follow the grinder manufacturer's guidance and ensure appropriate coolant is used to protect the diamond coating from thermal damage.
