The Precision Twist QC91P long-length drill bit is a parabolic flute design, 135-degree radius, split-point, round shank drill bit made of HSS with an uncoated (bright) finish. It is suitable for drilling to a depth up to six times the diameter of the drill. Good for portable or machine drilling. The shank diameter is the same as the drill size. It was designed for drilling holes into a wide variety of metals and synthetic materials with best performance in steel and cast iron. The QC91P series has a wide land parabolic flute design that enhances chip (also called swarf) formation and evacuation. Coolant has a better flow to the drill point for heat dissipation, and can be used at higher speeds and feeds for increased productivity. It is recommended to use a constant heavy feed rate... Less

The Precision Twist 1511 long length, 118-degree conventional point, general-purpose round shank drill bit made of high-speed steel (HSS) with uncoated finish is suitable for drilling holes to a depth up to 15 times the diameter of the drill size. The shank diameter is the same as the drill size. The 1511 series has a type N flute form (a regular helix angle of 21 to 34 degrees) which is good for drilling in a variety of materials, such as metal, wood, and synthetics. For drill bit sizes larger than 17/32 of an inch (13.49375mm/0.5312 5) inches, the drills have a black oxide (also called steam tempering) finish. This finish gives a strongly adhering surface treatment that acts to retain cutting fluid and prevent chip to tool welding, reducing the formation of a built-up edge. All other... Less

The Precision Twist R88CO jobber-length drill bit is a 135-degree, split-point, heavy-duty, round shank drill bit made of high speed steel (HSS) and cobalt with a gold oxide finish. They meet NAS 907 type D aircraft industry specifications for heat resistance and use for drilling hard, tough materials. Best performance is with drilling into hardened, tempered alloy steel, nodular graphite malleable cast iron, titanium, and alloyed nickel. It is suitable for drilling to a depth up to four times the diameter of the drill. The shank diameter is the same as the drill size. While the R88CO series was designed for the aircraft industry, they also work well for drilling into a variety of materials. The 135-degree split point drill geometry helps ensure an accurate hole by reducing walking when... Less

The Precision Twist R10H jobber-length, uncoated bright finish, general-purpose, round-shank drill bit drills holes into a wide variety of metals and synthetic materials. It can drill to a depth up to four times the diameter of the drill size. The shank diameter is the same as the drill size. The R10H series has a type W flute form, with a quick helix (35- to 45-degree) angle, with best performance drilling into copper, aluminum magnesium, and thermoplastics. Uncoated (bright) tools have no finish or coating. They are a common choice for drilling deep holes in materials of low tensile strength. Drilling, or hole making, is the most common metalworking operation in the world. Twist drill bits are the most common type of drill bit used. Twist drill bits are commonly used to drill holes...

Precision Twist Drill Bits are designed for use in multiple-spindle drilling heads where adjacent spindles operate alternately left- and right-hand. Made of high-speed steel, you can use these drill bits in screw machines for drilling while the spindle is revolving in the left-hand direction. Also for extracting bolts, screws, and studs. The shank diameter is the same as the drill bit size. Bits can handle most materials.

The Precision Twist QC21P jobber drill bit is a parabolic flute design, 135-degree radius, split-point, round shank drill bit made of HSS with an uncoated (bright) finish. It is suitable for drilling to a depth up to four times the diameter of the drill. Good for portable or machine drilling. The shank diameter is the same as the drill size. It was designed for drilling holes into a wide variety of metals and synthetic materials with best performance in steel and cast iron. The QC21P series has a wide land parabolic flute design that enhances chip (also called swarf) formation and evacuation. Coolant has a better flow to the drill point for heat dissipation, and higher speeds and feeds for increased productivity. It is recommended to use a constant heavy feed rate while drilling. This...

Precision Twist taper length drill bits have longer flutes and a longer overall length than jobber twist drill bits, which allows for deeper drilling. The shank diameter is the same as the drill bit size. High speed steel drill bits are for use with a wide variety of materials including steel, cast iron, and forgings. Cobalt steel drill bits provide better heat and abrasion resistance for high tensile alloys, stainless steels, and other difficult-to-machi ne metals. Their self-centering 135 degree point won't walk or skid when starting a hole, penetrates faster, and produces smaller chips.
