6.8mm HSS COBALT JOBBER DRILL BIT FOR DRILLING HARD METALS STEEL, DIN338

Product Information

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. For effective use the increased hole size should be no greater than two thirds of the starting hole size. An experienced operator can utilise a higher torque impact wrench or setting (if variable speed) to increase the speed of the job.

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.Manufactured to DIN338 standards, with a 135 degree split point tip for spot drilling without pre-centring. right-hand cutting twist drill bit, type N, drill bit tip 136 degrees, split point manufactured to DIN 1412 C, diameter tolerance h 8.

FeaturesGeneral purpose drills which are designed to drill steels with tensile strength up to 1,000N/mm2, cast steel, grey cast iron, malleable cast iron, nickel brass and graphite.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. 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. General purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite.

As major international supplier, Dormer insist on its products surpassing all relevant independant performance standards. The following are trademarks for one or more DEWALT power tools, accessories, anchors and concrete adhesives: The yellow and black color scheme; the “D”-shaped air intake grill; the array of pyramids on the handgrip; the kit box configuration; and the array of lozenge-shaped humps on the surface of the tool.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. Impact wrench driven drill bits will transfer less torque then a conventional drill bit used in a rotary drill, meaning less fatigue for the operator. Suitable for drilling steel, cast steel, alloyed and unalloyed, grey cast iron, spheroidal iron, sintered powder metal, German silver and graphite. Turbocharge your drilling performance by using this revolutionary tool with an impact wrench or impact driver.
