Precision Twist Drill 091488, 1-7/32x22 Diameter 6x22 OAL 118 Degree High Speed Steel Bright/ST Reduced Shank Drill Bit

Description

Reduced shanks are smaller than the drill diameter, so they can drill holes larger than the typical chuck capacity. The flutes of the drill bit act a passageway for chip extraction from the hole and for coolant to enter the hole. It can drill to a depth up to four times the diameter of the drill size. Precision was founded in 1952 in Crystal Lake, Illinois. The Precision Twist R56 Jobber-length, uncoated, general-purpose, round shank drill bit drills holes into a wide variety of metals and synthetic materials with performance with steel, stainless steel, cast iron, titanium, and nickel. Together, the Precision and Dormer brands represent a new, streamlined organization that provides a strong North American tool brand for high productivity Carbide and HSS drill and tap products. Flute length is three inches, overall length is six inches, with a half inch, reduced shank. Black oxide also helps to prevent buildup and welding of material on the cutting edge when working with iron and steel. These are sometimes called Silver & Deming drills; they used to be made by Silver & Deming in the late 1800s, but nowadays, its come to mean any reduced shank twist drill bit. These drill bits have a right hand twist that brings the chips up and away from the cutting edge. Combination black oxide and bright finish improves lubricity, resists corrosion, and will not chip or flake off. Twist drill bits are the most common type of drill bit used.
