Abstract

The utility model refers to a cutter for woodwork, involving a flat woodwork drill. Concretely, the drill includes handle and flat cutter drill. Forepart of cutter drill is an isosceles triangle. Two isosceles of this triangle are drill edge. Tapping screw groove is available on the side face of drill edge. In conclusion, the utility model features scientific structure, convenient processing, smooth cutting with the help of drill edge with tapping screw groove, reduces cutting resistance, improves cutting efficiency and greatly prolongs drill service life.

Description

Woodworking flat drill
Technical field
The utility model belongs to carpenter's cutting tool, relates to a kind of Woodworking flat drill.
Background technology
Existing Woodworking flat drill generally comprises a flat cutting head, and the blade shape on the cutting head is different, but exists defectives such as cutting resistance is big, chip removal is not smooth, service life is low mostly.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, and cutting resistance is little, stock-removing efficiency is high, the Woodworking flat drill of long service life.
Woodworking flat drill of the present utility model is made up of shank and flat cutting head two parts, and the leading portion of cutting head is isosceles triangle, and two waists of isosceles triangle are cutting edge, have the tapping screw thread groove on the side of cutting edge.Near most advanced and sophisticated part, one section flat segments that does not have the tapping screw thread groove can be set also in two cuttings, as the cutting guide section.
The utility model is rational in infrastructure, and is easy to process, owing to adopt the cutting edge that has the tapping screw thread groove, makes working angles more smooth and easy, reduced cutting resistance, improved stock-removing efficiency, thereby can prolong its service life greatly.
