  • Tungsten carbide body holds hardness at HRC 55
  • Coated shank options 3.175 mm to 8 mm fit multiple holders

Right-Angle Drill for CNC Milling

The YINGHUA tapered ball nose end mill is a right-angle drill designed for CNC milling and engraving tasks. It suits industrial operators and workshop technicians who need a coated tungsten carbide cutter for precision profiling. The tool is sold new and intended strictly for professional cutting applications.

Shank Options and Safety Constraints

Installation requires matching the cutter to a collet or chuck that accepts a shank diameter of 3.175 mm, 4 mm, 6 mm or 8 mm. Total length ranges from 38 mm to 100 mm so the user must verify reach before starting a job. The product is not for anyone under 18 years and must only be used for industrial cutting or engraving work.

Hardness Retention During Extended Cuts

The tungsten steel body carries an HRC55 hardness rating that resists wear during sustained milling passes rather than only short engagements. Coated flutes help evacuate chips when the cutter runs at depth for longer periods. Performance stays consistent across the full 38 mm to 100 mm length range without premature edge breakdown.

Questions about this item

How can I verify the R0.5 tapered ball nose is cutting correctly after installation?

Check for smooth chip evacuation and a uniform surface finish on the workpiece; the tungsten carbide coating should show even wear without chipping after the first test pass.

What comes in the package and what must I supply separately?

The box contains one ball nose end mill; you must provide a compatible CNC collet or holder matching the shank diameter you select.

Which shank diameter — 3.175 mm, 4 mm, 6 mm or 8 mm — should I choose?

Select the shank that matches your machine's collet size; 3.175 mm suits 1/8-inch holders, while 4 mm, 6 mm and 8 mm fit standard metric collets.
