Concrete Drill Bit Irwin SDS+ 8 mm 10501973

Irwin SDS+ 8 mm 10501973 concrete drill bit is designed for drilling into concrete, masonry and natural stone with rotary hammers that accept SDS+ shanks. The 8 mm diameter offers a practical balance between drilling speed and hole precision, suitable for creating anchor and dowel holes as well as through-holes in installation and construction tasks. The SDS+ shank provides secure retention in the chuck and allows quick bit changes without additional tools.

Advantages

The bit combines a carbide tip geometry with a reinforced flute profile to deliver consistent cutting performance and efficient dust evacuation during drilling. SDS+ shank compatibility ensures stable connection to compatible rotary hammers and reduces slippage under load. The 8 mm size is widely used for fixing work, offering predictable hole dimensions for anchors and dowels while keeping drill time and vibration at a practical level.

Suitable for

• Drilling anchor and dowel holes in concrete and masonry
• Through-holes for cables or pipes in thin concrete and block walls
• General-purpose installation and repair work on construction sites
• Trade and professional use with SDS+ rotary hammers

Key specifications

• Diameter: 8 mm
• Shank type: SDS+
• Primary materials: concrete, masonry, natural stone
• Tip: carbide cutting tip
• Application: rotary hammer drilling

How to use

Fit the Irwin SDS+ 8 mm bit into a compatible SDS+ rotary hammer until it locks in place. Select the hammer drilling mode and apply steady forward pressure while allowing the tool to do the work; avoid excessive force that can overheat the bit. For deeper holes, withdraw the bit periodically to clear dust and improve cutting efficiency. After finishing, remove the bit by pulling back and rotating if necessary, and inspect the cutting tip for wear before the next use.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask when drilling concrete. Match drill speed and hammer impact settings to the material and hole depth, and replace the bit once the carbide tip shows significant wear or reduced drilling performance.
