DLTHDK600 series-Inner Cooling Twist Drills for General Purpose
Literal statement:
Carbide drills provide faster cutting rates, longer tool life, better positional and dimensional accuracy and improved surface finish. Slot and pocket milling often creates chip evacuation problems, especially on vertical machining centers. Re-cutting chips can cause end mill failure. Coolant-through end millshelp evacuate chips from the cutting zone. This eliminates the problem or re-cutting chips.
Features:
- Suitable for drilling steel, stainless steel, cast iron, non-ferrous material.
- Stub chisel,excellent self-center capability.
- Radial point, smaller cutting resistance.
- Lip chamfer, higher feed rate, higher efficiency.

Attention:
- Make sure work peice and machine are stable and use a precision holder, use hydraulic chucks, high quality collet chucks.
- Make sure total indicated run-out(TIR) is less than 0.02mm.
- The recommended cutting condition is suitable for apply water soluable.
- If the tool size is not in the table. Please refer to the table closet to the blade diameter size selection of cutting parameters, adjust cutting parameters according to actual working conditions during processing.
