Description
Technical Field
The utility model relates to a woodworking tool, in particular to a spiral tool with a chip removal structure.
Background
Generally, the extending direction of the grooves of the woodworking tools is mostly parallel to the extending direction of the tools, in other words, the grooves are all formed in a linear manner, however, the chip removal performance of the tools is poor and the resistance encountered in the machining process is large, so a tool capable of improving the chip removal performance and reducing the resistance is required.
SUMMERY OF THE UTILITY MODEL
The utility model provides a spiral cutter with chip removal structure, its main aim at promote the chip removal performance of cutter, reduce the life that the processing resistance promoted operating speed, efficiency and increased the cutting edge.
In order to achieve the above object, the utility model discloses spiral cutter with chip removal structure, include:
a cutter handle part which is cylindrical;
a blade part connected with one end of the blade part to define the blade part and the blade part to be connected and extended along a longitudinal direction, and the outer surface of the blade part is provided with at least one spiral groove and a blade.
Preferably, the number of the spiral grooves is one, two or three, and when the number of the spiral grooves is plural, the spiral grooves are independent of each other.
Preferably, a spiral portion is disposed between the grooves, and the spiral portion has a plurality of flutes arranged along the longitudinal direction.
By the aforesaid, the utility model discloses spiral cutter with chip removal structure mainly sees through making this blade portion have an at least spiral helicine slot, and then promotes the chip removal performance of cutter, reduces the processing resistance.
