Abstract: A power drivable chuck 30 includes a body 72 which is formed with a shank-receiving opening 34 having a triangular cross section. A spring 104 is located about a forward section 78 of the body 72, and is captured within a chamber 102 between a base surface 98 of a sleeve 76 and a forward surface 100 of an intermediate section 80 of the body. A ball 90 is located in a passage 86 formed through the body 72 from an exterior surface 96 to the opening 34. A pair of slots 106 and 108 are also formed in the body in communication, and aligned, with the passage 86 on opposite sides of the passage. The ball 90 is formed with a through hole 112 and receives a pin 114 therein, with opposite ends of the pin extending from the ball and into respective ones of the slots 106 and 108. The spring 104 engages and normally urges the opposite ends of the pin 114 against the base surface 98 of the sleeve 76 normally to extend a portion 90a of the ball 90 into the opening 34 for locking a shank 42 within the opening.

Abstract: A multiple orientation hand saw is provided including a plurality of blade mounting configurations including a first blade mounting section for supporting a blade in a vertical orientation on the handle and a second blade mounting section for supporting the blade in a cross-cutting orientation.

Abstract: A tool pouch having a pocket with an opening to receive certain items. The pocket includes a magnetic member near the top of the pocket for holding items received in the pocket. The magnetic member assists in arranging items in the pocket.

Abstract: A large diameter self-feed wood bit is provided including a feed spur having a coarse spur thread of approximately 1.75 millimeters and a 20-degree main cutting edge relief angle. The main cutting edge relief angle complements the coarse self-feed thread pitch for faster, more efficient drilling of large diameter holes in wood.

Abstract: Significantly improved resistance to breaking while drilling in metal can be realized in twist drill bits having a web thickness taper which is about twice the web thickness taper specified in Standards and in common use in the industry. This creates much shallower flutes and flies in the face of conventional wisdom in the art which holds that the web taper rate should be low to maximize the amount of flute volume available to convey chips and sawdust out of the hole. A flute length of about 1/2″ less than the flute lengths specified by the Standards makes it possible to have such a large taper rate but still control variations in tolerances for the flute length. It also provides a marking zone for placing size indicia on the drill bit shank outside the portion which is gripped by the chuck jaws of a power drill.
