The Dormer A520 HSS TiN ADX Stub Drill Bit is a high-performance tool engineered for precision and durability. Designed with a Titanium Nitride coating, this stub drill bit offers exceptional wear res more→istance and heat dissipation, ensuring extended tool life and consistent cutting efficiency. Made from high-speed steel, it provides robust performance across a variety of materials, including steel, aluminium, and plastics. The A520 features a 130° split point that ensures accurate and quick starts, minimising bit walking and enhancing drilling precision. The ADX geometry optimises chip removal, reducing friction and heat build-up, making it ideal for high-speed drilling applications. Its shorter …

Long Lifetime - The HSS Twist Drill Bit Cobalt provides long-lasting performance when drilling stainless steel. This extended lifetime results from a cobalt alloy content of 5% and fully ground HSS (h more→igh-speed steel), which provides excellent surface quality, wear resistance and heat protection. Equipped with two cutters and two flutes, chips are removed quickly to make the bit last even longer. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. This drill bit works with alloyed and non-alloyed steel, stainless steel, cast iron, cast steel and acid- and heat-resistant steels. It has a cylindrical shank system (…

These high-performance Faithfull Tungsten Carbide Tipped Drill Bits fit into SDS Plus chucks which provide a particularly secure non-slip grip that transmits maximum power for rotary percussion drilli more→ng, mainly into concrete.The SDS Plus bits ensure maximum power transmission due to their unique fluted shaft. This effectively removes situations where a perfectly serviceable cutting edge is rendered useless by a worn shank. The SDS Plus system also enables faster changing of drills using a quick release keyless chuck.For use in bricks, blocks, concrete containing aggregates, marble and hard stone, and other hard masonry materials.
