Twist drill bit Irwin 10502047 — diameter 2.2 cm, 1 pc

Irwin 10502047 is a single twist drill bit with a 2.2 cm diameter supplied as one piece for use with hand and cordless drills. The bit features a standard spiral flute geometry for controlled material removal when producing a 22 mm hole. It is intended for general drilling tasks where a 2.2 cm hole is required and can be used on a range of common building materials.

Advantages

The single twist design provides reliable chip evacuation and stable drilling performance. A compact, extra-short head concentrates cutting forces at the tip to improve durability and reduce clogging by directing dust into the flute. The bit’s geometry supports comparatively fast drilling in masonry and concrete when used with a suitable hammer-drill mode, and the product is supplied as a single unit for straightforward replacement and storage.

Suitable for

• Drilling 22 mm holes for anchors and fixings in brick and block
• Creating clearance or passage holes in masonry and concrete
• General-purpose drilling where a single 22 mm twist bit is required

How to use

Install the Irwin 22 mm twist drill bit securely in the drill chuck and set the drill to the appropriate speed and hammer mode if drilling into masonry or concrete. Mark the drilling point, start at low speed to establish a guide, then increase speed and apply steady pressure. Periodically withdraw the bit to clear debris from the hole and allow the bit to cool. Replace the bit when wear or damage reduces cutting performance.

Usage recommendations

Use a hammer drill for efficient results in brick, block and concrete; wear appropriate eye, ear and dust protection during drilling and ensure the workpiece is secured. For optimal chip removal and tool life, clear debris regularly and avoid excessive side loads that may bend or dull the bit.
