Masonry & Concrete Drill Bits - Free UK Delivery Over £25 - Buy Online | Zoro

The Irwin masonry drills bits are designed for fast and efficient drilling in brickwork, concrete and breeze block, especially with cordless drills. They drill up to 60% faster than competitive drill bits whilst maintaining the same high durability.  The single flute design ensures faster dust removal for increased drilling speed, with the unique, pressed diamond-ground carbide tip allows for aggressive cutting and the carbide tip design also ensures 20% longer life compared to previous Irwin masonry drill bits. The bits are made with a chrome vanadium body with high carbon content which allows more hardening and a stronger bit for maximum rupture strength.

The Irwin HSS Pro Drill Bit manufactured from high quality HSS steel. They have precision ground cutting edges for fast drilling and perfect finishing, a ground flute for maximum accuracy and fast chip removal and a universal 118º point shape for drilling a wide selection of materials.

The Irwin HSS Pro TiN drill bits are primarily designed for drilling metal and harder, tougher alloys. Compared to traditional HSS twist drill bits, speed can be increased by 40 -60% and feed by 10 -20% without reducing the life time of the drill bit significantly.  TiN is also a poor conductor of heat, so the heat generated during the drilling process is diverted into the chips and coolant and less into the drill bit.  These drills have a 135° split point grinding tip which ensures perfect centring and reduced drilling pressure.  The drill bit body is manufactured from high quality HSS steel coated with 2.5µ Titanium Nitride (TiN), the TiN coating has a hardness of app. 80 HRC and is very resistant to wear. TiN has a low coefficient of friction, this results in less power being consumed and less heat generated during the drilling.

The Irwin Metric TCT (Tungsten Carbide Tipped) Drill Bits offer precision drilling with stationary machines in hardened steel, cast iron, bronze alloys and manganese alloyed steel. The C2 Carbide Tip will drill hardened material up to a hardness of 50 Rockwell C and is four facetted ground for low drilling pressure and perfect centring. The body of the drill bit is made from Chrome Vanadium Steel, hardened to 56 Rockwell C.  A coolant should always be used when drilling with TCT twist drill bits. Irwin suggest the use of a 3- 6% emulsion. The coolant will extend the lifetime of the drill bit.

The IRWIN® Speedhammer Quad Drill Bit is ideal for drilling plug and anchor holes in masonry, all types of stone and concrete. Its 4-cutter geometry, drills a more concentric hole for the best fixing retention.  The full head carbide tip offers the highest levels of drilling life and durability. A unique bonding system connects the solid carbide head to the 4-flute spiral. This design provides faster, more efficient dust removal. The specially engineered grooves are designed to minimise friction, resulting in increased speed and longer life.  Manufactured in Germany with premium steel. Meets PGM standards for drill bits used for anchor fixing.
