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 -2 more→0% 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 …

Fast Drilling-Accuracy - The Auger Bit is ideal for fast drilling-accuracy when producing through-holes, pre-drilling for rafter nails and drilling deep dowel holes in wood. The heavy-duty self-feedin more→g tip pulls the bit through completely, which allows for quick and effortless precision-drilling. Straight holes and a high chip removal rate and increased speed are made possible by the bit's optimised low-friction flute geometry with a solid centre. Its optimised scoring spur and precision-ground main cutting edge produce accurate holes. It is ideal for use in the ancillary building trades, for carpenters and roofers, and is suitable for soft and hard wood This drill bit has a hexagonal shank …

Highly Efficient Drilling - The SDS plus-5X Drill Bit offers highly efficient drilling in reinforced concrete. The geometrical form of the 4-cutter head prevents jamming and breakage for optimal resul more→ts. The “turn-angle” head and the large and short dust removal channels within the 4-flute design provide fast dust removal so the bit can slice through concrete and rebar quickly with reduced wear. For efficient work and exact hole diameters, the centring tip guides drilling from the start, to prevent wandering, which can falsify the hole diameter. The bit is intended for use on masonry, concrete and reinforced concrete. It is compatible with rotary hammers with SDS plus holders. As proof of qual…
