Tungsten Carbide Step Drill Bit
Features:
Drilling and chamfering
Smooth chip evacuation
Preferred tungsten steel
Sharp and practical
Advantage:
1. Large chip flutes can effectively ensure smooth chip removal and improve machining efficiency
2. Nano-coating on the cutting edge, nano-coating can reduce the loss of the tool, the tool is more wear-resistant, reduces the number of tool changes and also has the function of heat insulation
3. Cemented carbide
Using fine-grained tungsten steel base material, it has higher hardness and better bending strength, the tool is more wear-resistant, not easy to chip and break, and has a long service life
4. Easy to operate chamfering
The chamfered shank layout is easier to clamp.
Tips for Taking Care of Step Drill Bit
If you can manage to take proper care of your tool, it will serve the purpose for a long time. This way, you won’t have to spend extra money on buying a new kit soon. Now, is it too challenging to take good care of a step drill bit kit? Not at all, it’s as easy as it can be. Now, let’s learn how to do it right.
Step 1: You need to clean the bits at a regular interval during the work. Otherwise, it will be prone to damage faster than expected.
Step 2: You have to wipe the bit once you are done with the work.
Step 3: Scrub any debris off the bits by using a toothbrush.
Step 4: You can apply machine oil afterward to the bits.
