Abstract

The invention discloses a scale type woodworking drill, which comprises a drill bit body, wherein scale lines are arranged on the drill bit body; two or more colors of scale lines are arranged on the drill bit body at intervals; and the intervals of the same color are equal. By adoption of the scale type woodworking drill, the depth of a drilling hole can be quickly obtained for controlling. The scale type woodworking drill is particularly applicable to quick and accurate drilling of holes which are same in aperture and different in depth. A drill bit of the scale type woodworking drill has a drill tip, so the whole guidance of the drill bit is good, and the holes which are drilled cannot deviate; and a spiral front knife surface on the drill bit is recessed, so chips can be removed, friction and resistance are reduced at the same time, and the holes can be more easily drilled.

Description

technical field [0001] The invention relates to a cutting tool for wood processing, in particular to a ruler type woodworking drill. Background technique [0002] A drill is a tool used to drill through holes or blind holes in solid materials and to ream existing holes. Commonly used drills mainly include twist drills, flat drills, center drills, deep hole drills and casing drills. [0003] Using the existing drill bit, it is generally difficult to know the depth of the drilled hole, and further measurement is required, and the drilled hole is prone to deviation. [0004] In addition, an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different elements added and appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and non-magnetic properties ...
