An acronym for High-speed steel, HSS is generally the go-to type of steel needed for drill bits due to their excellent heat resistance at high speeds. As a standard drill can spin upwards of around 500 - 700rpm, the friction can cause a substantial build-up of heat.

As major international supplier, Dormer insist on its products surpassing all relevant independant performance standards. I used this to drill through a Shimano MTB bicycle crank bolt after it had defeated my cheap metal drill bit. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data.Precision engineered steel drill bits, with 5% cobalt shaft, for use on tough materials and hard steel, including stainless steel. Metal drill bits ground from solid extremely heat resistant cobalt-alloyed high speed steel produced according to DIN 338. These precision-ground drill bits enable up to 40% faster drilling and up to 50% lower feed pressure than standard-ground HSS drill bits with a chisel edge.

Designed as a twisted drill bit, these attachments guarantee excellent performance and will be an asset to your application. Made from cobalt alloy, these drill bit are highly durable and heat resistant providing extended the life of the drill bit. Note: Due to the nature of their application, accessories and consumables don't have a wear and tear guarantee or warranty. Precise response when positioning the bit due to its split point and 135° point angle as well as excellent dimensional accuracy also characterize this drill bit. As an example, a mechanic drill bit will have a much shorter flute and therefore have a much smaller overall length.

I blunted it yesterday after my 16th hole in mild steel sheet (re-drilled 6mm holes to hold casters). For the best outcome, please provide detailed courier instructions and a contact number that we can pass on to the courier. 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. 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. The Irwin Metric HSS Cobalt Drill Bits are perfect for drilling stainless steel and other high alloys.
