Rotary SDS+ Drill Bit Irwin 16 x 100/160 mm for Hammer Drills, Carbide Tip

Irwin Rotary SDS+ Drill Bit 16 x 100/160 mm is designed for drilling clean, accurate holes in concrete, masonry and natural stone with SDS+ hammer drills. The bit features a carbide tip engineered for improved wear resistance and sustained cutting performance, with a working length of 100 mm and overall length of 160 mm to reach moderate depths while keeping tool balance and control. This drill bit is intended for general construction tasks where a reliable rotary percussion tool is required.

Advantages

The carbide tip increases durability and maintains cutting edge sharpness under repeated impact drilling. The SDS+ shank provides secure engagement and quick bit changes with compatible hammer drills. Optimised flute geometry removes debris efficiently to reduce clogging and improve drilling speed. The 16 mm diameter is a common size for anchors and through-fixings, offering predictable hole dimensions for mechanical fixings and service installations.

Suitable for

• Drilling holes for anchors and plugs in concrete and masonry
• Installing electrical conduits and plumbing through solid walls
• General construction and renovation work requiring rotary-percussion drilling

Key specifications

• Diameter: 16 mm
• Working length: 100 mm
• Overall length: 160 mm
• Shank type: SDS+
• Tip material: carbide
• Application: concrete, masonry, natural stone

How to use

Install the bit into an SDS+ hammer drill by inserting the shank and ensuring it locks in place. Select the hammer drilling mode and apply steady pressure while allowing the tool to perform the cutting action; avoid excessive lateral force. For best results, start at low speed to position the hole then increase speed as the bit progresses. Periodically withdraw the bit to clear dust and debris from the hole and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment including safety glasses, ear protection and a dust mask. Match drill speed and feed pressure to material hardness, and allow the carbide tip to cool between prolonged drilling cycles. For precise anchor fittings, verify hole depth and diameter against fixing manufacturer recommendations before installation.
