摘要： A hole cutter has a substantially cylindrical blade body defining a blade body circumference, a cutting edge formed on one end of the blade body, and an axially-elongated slot formed through the substantially cylindrical blade body. The axially-elongated slot is configured to receive chips flowing from the cutting edge within the interior of the blade body and (i) into the slot, and/or (ii) through the slot, to prevent the collection of such chips within the interior of the blade body and/or at an interface between the blade body and work piece. The axially-elongated slot defines a first end adjacent to the cutting edge, a second end axially spaced further from the cutting edge, and a slot area. The hole cutter further defines a total slot area to blade body circumference ratio within the range of about 0.1 to about 0.3 depending on the size of the hole cutter.

摘要： A hole cutter having an extruded plate cap and methods and apparatuses for making such caps and hole cutters. The plate cap has planar opposing external and internal surfaces with an extruded hub extending axially inwardly from the internal surface. An aperture extends axially through the hub from the external surface. At least a portion of the aperture can be threaded for threaded engagement with a driving arbor. The hub is long enough so that the threaded portion contains at least two full threads. A blade body with a cutting edge is attached to the cap to form a hole cutter.

摘要： A utility knife blade comprising a blade body defining a first side, a second side opposite the first side, a back edge and a cutting edge opposite the back edge. The cutting edge includes a plurality of serrated portions and substantially non-serrated portions. The blade further defines two opposing lateral edges extending between the back edge and the cutting edge. A plurality of score lines laterally spaced relative to each other along the cutting edge extend across at least one of the first and second sides of the blade between the cutting edge and the back edge, the score lines defining a plurality of blade segments therebetween. The score lines extend between the non-serrated portions of the cutting edge and the back edge so that the serrated portions avoid contact with the score lines to facilitate the breaking off of each cutting segment when desired.
摘要翻译：一种实用刀片，包括限定第一侧的刀片主体，与第一侧相对的第二侧，后边缘和与后边缘相对的切削刃。切削刃包括多个锯齿形部分和基本上非锯齿形部分。刀片还限定了在后边缘和切割边缘之间延伸的两个相对的侧边缘。沿着切割边缘相对于彼此横向间隔开的多个刻痕线延伸穿过切割边缘和后边缘之间的叶片的第一和第二侧中的至少一个，刻痕线在其间限定多个叶片段。刻痕线在切割边缘的非锯齿形部分和后边缘之间延伸，使得锯齿状部分避免与刻痕线接触，以便在需要时便于切割切割部分。

摘要： A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.
摘要翻译：孔切割器具有圆柱形刀片体，其包括切割刃和形成在刀片主体的侧壁内的一个或多个轴向细长孔。轴向细长的孔被构造成容纳穿过其中的诸如螺丝刀的杆。每个轴向细长的孔包括邻近切割边缘轴向间隔开的第一支点，与第一支点相比轴向间隔开比切割边缘更远的第二支点，以及可选地在第一和第二支点之间轴向隔开的第三支点。诸如螺丝刀的杠杆可以被插入到孔中并放置在每个支点上，以将块塞从叶片本体的内部拉出。
