Spade bits with angled sides
InactiveUS6957937B2Improve Chip EvacuationDrawback mentionedWood turning toolsTransportation and packagingEngineeringMechanical engineering
A spade drill bit has a shaft and a spade head portion arranged on the shaft. The head portion has a rearward facing bottom edge, two longitudinal sides and a forward facing cutting edge. The cutting edge has a pointed, generally triangularly shaped tip and outer ends. The longitudinal sides of the head portion are bent along a bend in a direction of rotation of the drill bit during operation, so that the outer ends are bent forwards in the rotating direction. The bend runs from a first position at one of the longitudinal sides, closer to the bottom edge than to the cutting edge, and to a second position at the cutting edge between the outer end and the tip.

Hard metal drill bit for use on a drill
InactiveUS6629805B1Reduce wearReduce frictionWood turning toolsTransportation and packagingBreaking strengthHard metal
The invention concerns a hard-metal cutting tip for use on a drill, particularly on a rock or concrete drill, including a drill point (3) extending through an axis of rotation of the drill, primary cutting edges (6) that slope downwardly on both sides, each composed of a primary land (4) and a primary flank (5), the primary flank (5) forming at the primary cutting edge (6) a primary lip clearance angle (14) with a plane perpendicular to the axis of rotation. To provide a hard-metal cutting tip that possesses high cutting, feed, bending and breaking strength and wear resistance, especially at its outer regions subjected to high peripheral speeds, the hard-metal cutting tip is realized such that the primary lip clearance angle (14) formed at the primary cutting edge (6) decreases with increasing distance from the drill point (3).

A bit for removing a broken fastener comprises a tip from which extend two or more notches 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 and on the other side by a non-cutting edge 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.

Throw-away tipped drill, throw-away tip, and drill main body
ActiveUS7168893B2Easily and reliably performEasy elastic deformationWood turning toolsTransportation and packagingEngineeringDrill bit
In a throw-away tipped drill, a slit is formed at the bottom surface of a tip attachment seat which faces towards the end of its axial line direction, with this slit extending towards the rear of the axial line direction. Furthermore, when seen from the end of the axial line direction, this slit is arranged as being displaced so as to be closer to a second end portion into which a shaft portion of a clamp bolt is threaded than to a first end portion which is pressed by a head portion of that clamp bolt. As a result, when, using the clamp bolt, the pair of outer side surfaces of the tip are pressed by the pair of internal side surfaces of the tip attachment seat, the pressing forces are mutually equal to one another.

The magnetized drill bit extension provides a socket that accepts bits of various diameters and indicates its location when concealed, as within a wall. The invention has a socket at the end of a drill bit extension with a strong magnet integrated into the socket. The socket accepts round, square, and square corner rounded shanks of bits. The magnet within the socket endures drilling through wood. The socket emanates a magnetic field from within a concealed location that deflects a compass, thus revealing the location of the extension within a wall. Alternatively, a magnet is joined to the spade of a drill bit to reveal its location when concealed.
