Top 8 Best 31/64 Drill Bit

Ideal for drilling in tough metal, including heavy-duty abrasive alloy metal drilling on hardened steel.. Made from industrial grade High-Speed Steel for increased durability. 8 Cobalt alloy is heat and abrasion-resistant. 135-degree split-point tip starts drilling immediately with less force and eliminates walking across the work surface. Bit has a straight shank.

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Gold and black surface treated for use in stainless steel and other hard metal drilling. 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. Heavy duty 135 degree split point.

Speed helix design for three times faster drilling than standard bits. Last 50 percent longer than high-speed steel. Easier drilling, reduced heat and extended drill bit life. Available in jobber length, stubby length, extended length aircraft, 12 In. reduced shank Silver and Deming. For use in steel, copper, aluminum, brass, oak, maple, MDF, pine, PVC, polycarbonate, acrylic, ABS, nylon and composite materials.

Strength Hardness Made with HSS 4241 steel, Rock wall Hardness Level HRC 60-62.. Package Size 5 Pieces in a plastic bag, Diameter 3164 inch, Total length 5-78 inch, Working length 4-38 inch.. Professional DIY Use For use on metal, wood plastics, Not For Use On Concrete Masonry Stainless Steel. Perfect match for workshop or service vehicles.. 135 Tip Twist Design Increases cutting speed with self-centering and prevents walking, clears chips and particles faster..

Ideal for general wood drilling and especially for making dowel holes. The lip and spur tip design helps to prevent tearing wandering on flat surfaces. Produces clean cuts.

COBALT STEEL - Manufactured from M35 cobalt steel, with molybdenum and cobalt added to create a hardened heat-resistant alloy, measuring Rockwell hardness up to 67, for much faster cutting and extra longer life span, with up to twelve times compared with an average HSS drill bit.. 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.. 2PC 3164 INCH FRACTIONAL BITS - The set includes 2pcs of M35 cobalt steel twist drill bits. Total length 5.87 Inch working length 4.37 Inch. Manufactured to German DIN338 standard. Packed in a plastic bag and a flat paper box.. 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.. 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 tool holding systems. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. Manufactured to national aerospace standard 907.

The product is 3164SplitPT Drill Bit. Easy to use. The product is manufactured in China. Pilot point tip starts on contact for clean, accurate holes and reduces lock-up on breakthrough. Pilot point tip reduces lock-up on break-through. Tapered web provides greater durability to reduce breaking. No spin shank eliminates the frustration of bit spinning in chuck. Note Sizes 116-inch to 1164-inch are split point drill bits Std jobber length fractional sizes.
