Product Description & Reviews

The Precision Light 321MDSET29 29-piece mechanic's length drill bit assortment contains 29 high-speed steel drill bits with a bronze and black oxide finish in inch sizes 1/16" to 1/2" (1/64" increments) with a self-centering 135-degree split point to penetrate material without a pilot hole. High-speed steel (HSS) provides hardness for wear resistance, while the bronze and black oxide finish reduces friction for higher drilling speeds than uncoated drill bits. The three-flat shank provides a more secure grip in drill chucks than a round shank. The assortment comes in a round plastic case with labeled compartments for identification and organization.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.Dormer Pramet manufactures cutting tools under the following brands: Precision Twist Drill, Dormer, Union Butterfield and Pramet.
