The Irwin auger wood drill bit has been designed for all general wood boring and offers a superior performance. The single spur cutting edge scribes the circumference of the hole for a smoother quality finish. The hexagon shank prevents slipping in a drill chuck or bit extension.  The solid centre provides extra rigidity whilst boring, the self-feeding screw point provides faster boring in both soft and hard woods and the fully hardened body from tip to shank provides extra durability.   

The IRWIN® SDS Speedhammer Plus Drill Bits are designed for SDS drilling. They drill exceptionally fast into brick, block, masonry, concrete and granite.  The patented, unique single flute design ensures efficient, speedy removal of dust and lower vibrations and 28% greater capacity meaning more efficient waste removal. They have a patented extra-short drill bit head which means the head takes 80% of the workload, ensuring higher durability and speed.

The bits have 25% more tungsten carbide for extra strength and they drill 25% faster than competitive drill bits with the same high durability. In addition, they have more aggressive cutting angles and self-centring for faster drilling.

Designed for high-speed precision drilling, it marks an end to the frustration that tradesmen experience when their drill bits strike a nail, frequently causing standard flat bits to become locked or break.
