M.Q.L-DRILL (ロングドリル)
Solid carbide long drill for deep hole
» Unique geometries provide high performance
» Increased rigidity and low cutting forces provide high hole quality
» Ultra-fine-substrate with TiAlN coating for high level of
wear resistance & toughness
The M.Q.L drill, especially for deep hole drilling up to 20xD, offers reliable machining with excellent cost saving. Its unique geometry coupled with its wide flute design and lapping on the flute optimize smooth chip evacuation and low cutting forces as well as cutting edges that resist chipping and breaking.
加工用途
- 自動車部品 (シリンダーブロック、クランクシャフト、コネクティングロッド等)
- 金型部品
- 工作機械部品
推奨加工手順
- Make a pilot hole with SHO drill (pilot drill diameter should be 0.03-0.05mm larger than long drill)
- Approach a pilot hole with low revolutions
- Start drilling with recommended cutting speeds & feeds and continue drilling without a pecking cycle
- After drilling, reduce the speed by over 50% and move the drill away from the bottom of the hole
