摘要: A bit for removing a broken fastener comprises a tip from which extend two or more notches (16) separated by traction or biting surfaces formed from two-sided frusto-conically-shaped regions. The surfaces are bounded on one side by a nonlinear cutting edge (14) and on the other side by a non-cutting edge (17) and are configured to cut into the fastener when the bit is rotated in a direction opposite to the fastener's direction of engagement. Specific embodiments include configurations where the cutting edges extend at different angles with respect to the bit axis, where the biting surfaces comprise a plurality of serrations, and where the cutting edges are separated by flutes which spiral along a longitudinally extending periphery of the bit.

摘要: A cutting tool insert having a controlled contact clearance behind the cutting edge which limits flank wear and allows more coolant near the cutting edge further allowing an increase in surface speed, feed rates, and tool life. The controlled contact clearance surface provides a first wear zone and a second wear zone, the first wear zone generated during operation of the drill insert allows the flank wear distance to grow from zero to the distance from the cutting edge to the controlled contact clearance surface, the second wear zone keeps the flank wear distance substantially constant until the controlled contact clearance surface is substantially worn away.

摘要: The present invention is a drilling system for cutting flat bottomed holes in work pieces. The tool has two opposing angled cutting edges (62, 64) extending upwardly to create an overlapping web (70) at the center. The angle at which the inner portion of the cutting edge (62, 64) is inclined is increased to create a center point on the cutting surface of the tool. The cutting edge (62, 64) has a rake surface with a positive rake angle (80) that lessens the forces on an insert (35), and also allows for better formation of chips of stock material being removed. Chip breakers (82) can be cut into the cutting edges (62, 64) of the insert (35), further aiding in the removal of stock material.

摘要: The present invention provides a novel drill insert having chipbreakers, or chip splitting grooves formed through the cutting surface. The cutting tool insert has a specialised geometry including a chip splitting groove formed at a negative rake angle. The chip splitting grooves increase the cutting efficiency of the tool while allowing the edge strength to be increased while also allowing higher feed rates.

摘要: The present invention relates to a V-notched web (66) formed on a drill insert (35) of a drill tool assembly (10). The V-notched web (66) allows greater stability and feed rates, while decreasing the heat generated at the insert tip. The present invention is provided by a drill insert comprising a drill insert body having at least two cutting edges, a web between the two cutting edges, and a web thinning notch formed on either side of the web. Each web thinning notch forms a notch edge having a positive rake angle.
