Effective in drilling tough, high tensile strength materials like stainless steel, inconel and titanium. 135 split point tip prevents drill from walking. Round shanks allow use with a wide variety of tool holding systems. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools performance is similar to uncoated tools. 6 overall length for drilling where extra length for reach is required.

Pilot point tip starts on contact for clean, accurate holes and reduces lock-up on breakthrough. No-spin shank eliminates the frustration of bit spinning in the chuck. Tapered web provides greater durability to reduce breaking. Size markings are located above the shank to prevent wearing away. Note Sizes 116-inch to 1164-inch are split point drill bits Std jobber length fractional sizes.

COBALT STEEL - Manufactured from M35 grade cobalt steel, with molybdenum and cobalt added to creates a hardened alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times when compared with an average HSS drill bit.. FOR METALWORKING - Particularly successful in cutting through hard metalshardness less than HRC38 such as stainless steel and cast iron, although they can be used for softer materials like copper and aluminium, too. Not for hardened steel high carbon steel. Try to adjust the RPM when it fails to penetrate.. SELF CENTERING - The 135quick-cut pilot split points are self-centering and can penetrate quickly with less pressure. The bits will not walk or wander. Straight shank allows for firmly holding and accurate centering, fit for standard drill chucks and regular round collet chucks.. 10PC SET - The set includes 10pcs of 1564 diameter M35 grade cobalt steel twist drill bits, packed in a plastic case for easy storage and carrying. Total lenght 3.86 inch working length 2.64 inch. Manufactured to German DIN338 standard.. DOWNLOADABLE USER GUIDE - We've summed up some tips of drilling metals, including a RPM chart for several common metals, based on our reviews and some articles on the internet. In most cases, our customers would get a much better result with these tips. Welcome to download..

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. For general purpose drilling in applications where extra length for reach is required, designed to perform in a broad range of materials in the iron and steel families.
