Quantity:  20PCS

Connection:Triangle Shank

Specification:

Triangle shank diameter: 10mm

Accessories: centre drill*2, hexagonal wrench*2, spring*3

Substrate height (total height without centre drill): 79mm;

Drilling depth: recommended below 15mm thickness, limit is 25mm

Application:

Drill holes in stainless steel, steel plates, profiles, castings, aluminium alloys, copper and other metal plates;

Stainless steel plate (thickness of 8MM or less), steel plate (thickness of 25MM or less), aluminium plate (thickness of 25MM or less), etc., generally is recommended for plates with a thickness of 15MM or less;

Features:

1. 1 set of 3 edges, including the outer edge, the middle edge and the inner edge, sharp and efficient

2. During the cutting process, each of the three edges is responsible for about 1/3 of the workload, and each blade has a cutting knife in the inner measurement, smooth chip removal, not easy to produce the phenomenon of chipping.

3. It can be used in table drills, magnetic drills, pistol drills and floor drills over 350W, and the triangular shank design provides strong and stable clamping force to minimise sliding in heavy duty cutting tasks.

4. Each hole drill is pre-oiled and packed in an aluminium case for rust-proof storage and easy access.

Note:

1. For different materials, use the appropriate RPM for the number of revolutions;

2. The material being cut must be fixed, no movement and vertical;

3. In the continuous high-speed drilling process, it is best to add emulsified oil or other cutting fluid;

4. If processing the material of more than 15mm thickness, please remove the spring before drilling;

5. After penetrating the material being cut, wait for a while before drilling, to avoid the moment of penetration, the edge of the hole drill and the material being cut to have a violent impact;

6. If there is any abnormality during the cutting process or the chip removal material is blocked in the chip removal groove, gently remove it and use it again;

7. The edge is relatively sharp, remember not to touch with your hands
