Product Information

North Berwick High School, East Lothian "All received and mechanical department are happy with the bits. Over the past two and a half years I have been using Tilgear for purchasing the tool kits for the Lee Marley Brickwork apprentices.

General purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite. PayPal Credit and PayPal Pay in 3 are trading names of PayPal UK Ltd, Whittaker House, Whittaker Avenue, Richmond-Upon-Thames, Surrey, United Kingdom, TW9 1EH.An experienced operator can utilise a higher torque impact wrench or setting (if variable speed) to increase the speed of the job. Its right-hand spiral and 118° point angle make it suitable for drilling into plastic, wood and metal.

Featuring a non slip shank, a no-walk tip for curved surfaces and a strong central core that improves fracture stability, particularly in freehand use (4. Having since moved on to two additional colleges I’ve always made sure we did business with Tilgear. An amazing experience so far 10/10 for service I must admit" - D Shah, Designed with Elegance UK "I have used Tilgear to supply us with goods since 2014 when I started as a Construction Technician.They have a patented hexagon shaped shank that makes them suitable for use with any standard 1/2” drill chuck for cordless or pistol drills. As major international supplier, Dormer insist on its products surpassing all relevant independant performance standards. FeaturesVersaDrive® TurboTip Impact drill bits are stepped tip bits that drill at twice the speed of standard bits without the need for pilot drilling while cutting a perfectly round hole. HSS-Co cobalt twist drills from Heller are equipped to tackle the toughest drilling jobs in stainless steel and metal. VersaDrive Impact wrench drill bits work by utilising the high torque rotary drive of an impact wrench in a conventional rotary drilling operation.

If you’re going to invest in a high quality HSS cobalt drill bit set, you need to know what you’re doing with it. right-hand cutting twist drill bit, type N, drill bit tip 136 degrees, split point manufactured to DIN 1412 C, diameter tolerance h 8.Drill Bits are ideal for drilling into cast iron, steel, alloyed and non-alloyed material up to 800N/mm². However, by default this process will utilise the impact operation (as opposed to rotary only) meaning a possibility of reduced drill bit life. Engineered with precision and crafted to perfection, this drill bit is your ideal companion for drilling tasks. The impact wrench mechanism should not engage or impact when drilling, if this occurs, too great drilling pressure is being used and should be reduced. The 5% added Cobalt means increased life and faster cutting than traditional HSS Drill Bits, therefore saving downtime in manufacturing.

Drill bit colour : polished Suitable for drilling in alloyed and unalloyed steel up to a tensile strength of 900 N/mm2, cast steel, cast iron, sintered iron, temperate iron, non-ferrous metals and hard plastics. Manufactured to DIN338 standards, with a 135 degree split point tip for spot drilling without pre-centring. For effective use the increased hole size should be no greater than two thirds of the starting hole size. VersaDrive TurboTip Impact drill bits are stepped tip bits that drill at twice the speed of standard bits without the need for pilot drilling while cutting a perfectly round hole.The drilling time when used with an impact wrench is slightly slower but comparable to a standard rotary pistol drill.
