Problem: Managing a large collection of jobbers drills is an added hassle when preparing for jobs. Solution: A handy portable set offers a convenient metal index and drill collection for all your needs.Stay Organized with this Value Pack of 115 Piece Jobbers Length Twist. Travers presents a value pack of high-speed steel jobber's drill bits from brand Rushmore USA and TTC for high-performance applications. The pack consists of a 3-in-1 combination of HSS series jobbers twist drills in fractional sizes ranging from 1/16 inch to 1/2 inch by 64ths; number sizes of #1 to #60, letter sizes of A to Z. All drill bits offered in this series are surface treated and appear to have a black oxide. The thin web on the drill penetrates the work hardening stainless fast enough to continually cut beneath the chip which is hardening from deformation. The heavy-duty core guarantees increased strength and reduced breakage. The unique spiral flute design improves chip ejection and coolant flow to the point. 118° self-centering split point allows aggressive cutting. The drills are capable of machining on various difficult-to-machine surfaces including cast iron, high silicon aluminum alloys, titanium alloys, nickel alloys. It significantly reduces friction and thereby, offers higher feed rates. The standard helix angle of 30° can wrap slowly and is used in drilling hard materials including brass. The overall tool length in fractional sizes is available in 6 inches and under. The tool has a round body shank to accommodate any common holders for use in CNC or hand-held applications. This USA Made brand offers quality affordable American-made tooling with the superior speed and feed that your applications require.
