Cemented Carbide Countersinks Introduction

Cemented carbide countersinks are processing tools which drills pointed is cylindrical cone or plane, a countersink cut tapered countersink drill.

Cemented carbide countersinks plane, cylinders, cones, and other surface machining on the end face of the hole. The processed hole machining cylindrical countersunk holes, conical countersunk holes and the end face of the boss, use cemented carbide countersink drill.

Cemented Carbide Counterbore Drill Introduction

Cemented carbide counterbore drill generally used for the hole of the semi-finishing or finishing for hinge or grinding before the expansion of the pre-processing or blank hole, a 3-4 edge with no chisel edge, the rake angle and a rear angle along the cutting edge of a small change in the machining guide effect, the axial resistance is small, the cutting conditions than drilling.

Cemented Carbide Counterbore Drill & Countersinks & Reamers

Cemented carbide counterbore drills are used for the premachining reamer used as a hinge or in front of the grinding hole, such as drilling, casting hole, forging hole and punching expand.Compared with drills, cemented carbide reamers have the following characteristics:

(1) Cemented carbide reamers are used to expand the existing hole, and therefore the cutting edge does not need to extend to the center, no chisel edge, to avoid the adverse impact of the chisel edge of the chips.

(2) The reaming margin is relatively small, shallow chip flutes large thickness center of drills , the high strength of the cutter body, good rigidity, the larger the amount of feed and the cutting can be employed.


(3) Cemented carbide reamers have many teeth. Generally they have 3 to 4 cutters, the oriented is good and cutting smooth.

Drilling & Cemented Carbide Drills

Hole machining is widely used in cutting. drilling can used in hole processing in the solid material.

In metal cutting, the proportion of hole machining, the need for extensive use of a variety of hole machining tools. Hole Cutter divided into two categories according to their use: a class of tool hole machined from a solid material, such as twist drill, flat drill, center drill and deep hole drilling, etc.; the other is the existing hole again hole machined hole machining tool, such as reamers, countersink drill, reamer and boring tools.

The Hole Cutter major cemented carbide drills, reamers, boring tools, broaches and composite hole processing tool. 

Boring & Cemented Carbide Boring Tools

Boring is a turning process to expand the inner diameter of the hole or other circular contour with cemented carbide boring tools, the boring processing applications generally range from semi-roughing to finishing, with the boring tool is usually single-edged boring cutter.


Boring generally carry out on boring machine, processing center and a combination of machine tools, boring mainly used in the processing box, bracket and stand on the workpiece cylindrical bore, threaded holes, holes, grooves and face; When using a special attachment.When boring can be processed inside and outside the spherical cone.

Cemented carbide inserts introduction

In order to ensure cemented carbide inserts both with turning tools supporting the use can be used alone, so said the model size marker with cemented carbide turning tools are uniform provisions. In order to be consistent with the marked cemented carbide inserts of different models of its size is uniform provisions.

For example, 01 cemented carbide inserts corresponding 31-type cemented carbide turning tools, 02 cemented carbide inserts corresponding 41 cemented carbide turning tools,09-C-type cemented carbide inserts cemented carbide turning tools corresponding 92, 09The corresponding 93-J-type cemented carbide inserts cemented carbide turning tools. In short, these carbide inserts models must cemented carbide turning tools with the corresponding model corresponding

Cemented carbide turning tools sizes

Cemented carbide turning tools have 7 sizes: 0 to 6. the larger turning tools sizes is, the greater value length, width, and height dimensions have. From right to left, followed by 31 cemented carbide turning tools is 1 to 6 of cemented carbide turning tools. It is easy to see from the figure of their length, width, height is not the same.
