Drillco 900 Series High-Speed Steel Taper Shank Drill Bit, Black Oxide Finish...
Product Overview
Size:
11/16"
Unit Count:
1
Size:11/16" | Unit Count:1 The Drillco 900 series long length drill bit is
made from high-speed steel with a black oxide finish and has a 118-degree
conventional point for drilling a range of materials. The length is slightly
longer than jobber length, allowing for deeper holes and longer reach. The
shank diameter is the same as the drill body. High-speed steel (HSS) provides
hardness for wear resistance, and the black oxide finish reduces wear while
promoting chip and coolant flow. The round shank accommodates most drill
chucks. The drill bit conforms to American National Standards Institute (ANSI)
specifications.Drill bits are cutting tools used to make holes in a range of
materials using machines such as handheld portable drills, machining centers,
and lathes. Drill bits come in a variety of lengths and types, the most common
of which is the twist drill bit. The round, twisted shaft of the twist drill
bit typically has two cutting edges and flutes. The helical twist of the
flutes brings chips up and away from the cutting edges and allows for coolant
to reach the cutting edges. Jobber length twist drill bits, the most common
length of twist drill bit, offer a good compromise of length and reach for the
widest range of materials and applications. Mechanic's length twist drill bits
(also called maintenance length) are a little shorter than jobber length and
less prone to deflection when drilling. Short length twist drill bits (also
called stub or screw-machine length) are the shortest and stiffest twist drill
bits, helping to reduce the chance of deflection or breakage when drilling.
Reduced shank twist drill bits (also called Silver and Deming drill bits) have
a shank that is smaller in diameter than its shaft, permitting drilling
machines with a 1/4", 1/2", or 3/4" drill chuck to create large holes. Long
length twist drill bits (also called taper length) are a little longer than
jobber length, allowing for deeper holes and longer reach. Extra-long length
twist drill bits (also called extension) are longer than long length twist
drill bits for greater reach or for drilling deeper holes.Drillco manufactures
cutting tools such as drill bits, reamers, taps, dies, annular cutters, end
mills, and burs. The company, founded in 1978, is headquartered in Baton
Rouge, LA.
