WC Fast U Drill 3 Times Diameter Indexable Adjustable 4mm/10mm/12mm/26mm U Drill Deep Hole Bit
Description of WC U drill
The WC U-drill is made of high hardness H13 steel and undergoes quenching, carburizing, grinding and other processes to make the U-drill; More sturdy and durable; Innovative spiral groove design, with an inner and outer groove ratio of 6:4; Smooth chip removal, less prone to chip blockage; Internal cooling double spiral water outlet, widened water outlet, larger flow rate, better cooling effect, updated blade angle, making cutting more efficient.

- In the initial drilling, it is recommended to use the cutting value in the middle range, and then adjust the cutting parameters (according to the tool wear) to achieve the best cutting effect. The above cutting parameters are for 2D and 3D types, and for 4D types, the drilling parameters should be correspondingly reduced by 15%.
- When the cooling method is only external cooling, the cutting speed should be reduced by 10%.
- For the processing of austenitic stainless steel, internal cooling must be used.
- When starting external drilling on the inclined plane, or when there are pre drilled and intersecting holes in the parts, or when drilling multi-layer plates, the feed rate needs to be reduced to about one-third of the recommended value.
Note
- When using the lathe, it is easy to crush and burn the U-drill when using it with a deviation from the center
- When using small-sized U-drills, high speed and high feed are required, because the lower the parameters, the greater the cutting resistance, and the situation of burning the tool is easy to occur

FAQ
Q1: Vibration?
Solution:
1. Minimize overhang as much as possible
2. Check if the power tools and parts are securely clamped
3. Increase feed rate
4. For soft materials, cutting speed can be increased
5. For hard materials, the cutting speed should be reduced
Q2: Cutting blockage?
Solution:
1. Increase the feed rate to crush the cutting
2. Increase coolant pressure
Q3: Blade breakage?
Solution:
1. Reduce the feed rate at the drilling inlet
2. Choose a softer blade material
3. Reduce feed rate
4. Check for correct assembly
5. For hard materials, the cutting speed should be reduced
