Features & Benefits • For drilling reinforced concrete, masonry, natural and artificial stone • 4 flute helix with maximum flute entry enables faster debris removal, with the core being reinforced for optimum impact and breakage stability • Solid two cutter head is flanked by two individual cutting tips delivering a fast and efficient drilling speed • Superior carbide grade and geometry ensures greater resistance to breakage and premature …

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 …

The Dormer A321 Heavy Duty HSS Drill is specifically designed for reliable performance in medium-depth drilling applications. Its tri-flat shank ensures a secure, non-slip fit in the chuck, making it more→ideal for both hand-held drilling and use with pillar drill machines. The drill's self-centring 135° split point minimises thrust force, ensuring efficient and precise drilling. Its steam and bronze-tempered surface finish enhances lubricity, reducing friction and wear during use. Engineered for versatility, this drill is well-suited for drilling into a wide range of thin-walled materials, delivering durability and consistent results. Features and Benefits • Steam and Bronze Tempered Surface F…
