Versatile high-performance solid carbide drill that can be used across a wide range of materials. With one drill for all materials, stock holding can be reduced and greater machine flexibility is offered leading to reduced set-up time.
The three most basic parameters for the hole are:
The hole type and required precision affect tool choice. Drilling can be affected by irregular or angled entry/ exit surfaces and by cross holes.
When the hole is analyzed, have a look at the workpiece material, component shape and quantity
Productivity is not only influenced by grade and geometry, but also by the ability to clamp the tool securely and precisely. For best stability and hole quality always use Coromant Capto or CoroChuck 930 with the shortest possible drill and overhang.
Minimum tool run-out is essential for successful drilling. The run-out should not exceed 0.02mm in order to achieve:
Coolant supply influences:
Internal coolant is necessary for hole depths larger than 3 x DC and for avoiding chip jamming.
External coolant can be used for shallow hole depths and good chip formation.
Chip formation and evacuation is a critical issue. Chip jamming is dependent on:
It affects hole quality, drill life/ reliability, drill breakages.
Cutting speed is the main factor affecting tool life.
For help on selecting the right tool.
Cutting speed, along with material hardness, are the main factors affecting tool life and power consumption.
Achieving good hole quality may require some extra attention. Here you can find some useful tips to get you started.
