Carbide-tipped Masonry Drill Bit Topex Punktak 9.4 x 127.5 mm 03A442

Topex Punktak 9.4 x 127.5 mm is a carbide-tipped masonry drill bit engineered for drilling into concrete, brick and natural stone. With a 9.4 mm working diameter and 127.5 mm overall length, the bit is intended for use with rotary and hammer drills to create anchor holes, install fixtures and perform general masonry tasks that require durable cutting performance and reliable chip evacuation.

Advantages

The carbide-tipped head provides enhanced wear resistance and maintains sharpness during repeated contact with hard substrates. The flute geometry is designed to remove dust and debris efficiently, reducing clogging and improving drilling speed. The steel shank offers torsional stability when used in both standard rotary and percussion modes, ensuring consistent hole size and alignment.

Suitable for

• Drilling anchor and fixing holes in concrete and masonry
• Installing electrical boxes, conduits and plumbing supports in brick or block walls
• Preparing holes for mechanical fasteners and dowels in stone and mixed masonry

Key specifications

• Diameter: 9.4 mm
• Overall length: 127.5 mm
• Tip material: carbide
• Shank type: straight steel shank for drill chucks
• Intended use: rotary and hammer/impact drilling in masonry

How to use

Secure the drill bit in the drill chuck and set the tool to the appropriate mode (rotary or hammer) according to the substrate. Mark the drilling point, start at low speed to establish the position, then apply steady pressure and use the hammer function for harder materials like reinforced concrete. Periodically withdraw the bit to clear dust and prevent overheating. Use appropriate personal protective equipment such as safety glasses, gloves and a dust mask.

Usage recommendations

For best results, match drill speed and hammer setting to the material: lower speeds and percussion for dense concrete, higher speeds for softer brick. Replace the bit when cutting performance decreases or the carbide tip shows visible wear. Use a vacuum dust extractor or intermittent withdrawal to reduce dust when drilling indoors.
