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 …

Maximum Precision - The HSS Twist Drill Bit Ground is for drilling through metal with maximum precision. The bit's exposed 135-degree self-centring split-point tip combines active cutting and perfect more→centring without wandering, delivering maximum precision. The split-point tip also eliminates any need to pre-punch or pilot drill for up to 10 mm. This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. This bit is designed for drilling holes in alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, malleable cast iron, non-ferrous metals and hard plastics.…

The Makita Performance SDS Plus range consists of European manufactured hammer drill bits with a patented high volume multi-flute that quickly channels the drilling dust from the hole, saving both tim more→e and money. Due to its aggressive design, the fast and durable carbide tip allows easy centering and spot drilling. Designed for regular professional use, providing excellent performance in the toughest of materials. Also excellent for drilling in high resistance materials such as Green Concrete or Engineering Brick. The unique reinforced flute geometry transfers more impact energy from the rotary hammer to the drill head, reducing stress for user and power tool. The design and technology innovations …
