Abstract
The utility model is a kind of drill bit reducing burr, comprise drillstock (1), drill bit (2), the top of drill bit (2) is oblique covering of the fan (3), the bottom of oblique covering of the fan (3) has cutter groove (4), cutter groove (4) is made up of vertical part (5) peaceful portion (6), the axis parallel of vertical part (5) and drill bit, and flat portion (6) are vertical with axial line, vertical part (5) is highly 3mm-4mm, and the width of flat portion (6) is 2mm-3mm.The utility model has the advantages that increase operating efficiency, reduce costs, reduce product burr.
Description
Technical field
The utility model relates to a kind of drill bit, particularly a kind of drill bit reducing burr.
Background technology
No matter drill bit is all widely used in the middle of mechanical field or life, the problem in hole on a lot of product can be solved, general drill bit is in punching, while completing hole, periphery in hole also can leave a lot of burr needs other grinding process, add operation, namely improve cost, and reduce efficiency.
Summary of the invention
The technical problem that the invention will solve is to provide a kind of drill bit increasing operating efficiency, reduce costs, reduce product burr.
The concrete technical scheme of the invention is: a kind of drill bit reducing burr, comprise drillstock, drill bit, the top of drill bit is oblique covering of the fan, the bottom of oblique covering of the fan has cutter groove, cutter groove is made up of peace portion, vertical part, the axis parallel of vertical part and drill bit, and flat portion is vertical with axial line, vertical part height is 3mm-4mm, and the width in flat portion is 2mm-3mm.
Because this drill bit is provided with cutter groove, during use, the bottom of drill bit can not be cut to the edge of product, so be not easy to produce burr.
The advantage of the invention is increase operating efficiency, reduces costs, reduces product burr.
Accompanying drawing explanation
Fig. 1: the main TV structure schematic diagram of the invention.
Detailed description of the invention
A kind of embodiment of the invention is described by reference to the accompanying drawings.
A kind of drill bit reducing burr, comprise drillstock 1, drill bit 2, the top of drill bit 2 is oblique covering of the fan 3, the bottom of oblique covering of the fan 3 has cutter groove 4, cutter groove 4 is made up of peaceful portion 6, vertical part 5, the axis parallel of vertical part 5 and drill bit, and flat portion 6 is vertical with axial line, vertical part 5 is highly 3mm-4mm, and the width in flat portion 6 is 2mm-3mm.
Because this drill bit is provided with cutter groove 4, during use, the bottom of drill bit can not be cut to the edge of product, so be not easy to produce burr.
The advantage of the invention is increase operating efficiency, reduces costs, reduces product burr.
