SKU CH-1YPG-PYZ4Q

A 0.20 mm carbide ball end mill with a 0.16 mm cut length for precision milling

  • Carbide construction resists wear for longer tool life
  • Ball nose profile creates smooth contoured surfaces
  • 20 mm diameter suits micro-machining tasks
  • 16 mm cut length enables precise shallow cuts
  • WXL coating reduces friction and heat buildup

OSG 3170015 Carbide Ball End Mill

This OSG carbide ball end mill carries part number 3170015 and measures 0.20 mm in diameter with a 0.16 mm length of cut. The tool features a WXL substrate and is designed for non-coolant-through operation. It suits precision milling tasks that require a very small ball-nose profile.

Suited to fine-detail milling and profiling

Machinists producing intricate contours, small-radius slots or detailed 3D surfaces will find this cutter appropriate. The 0.20 mm diameter limits material removal rates, so it is not intended for roughing or high-volume stock removal. Buyers who need larger diameters or longer cutting lengths should select a different tool.

Fits standard collets and shrink-fit holders

The shank dimension matches common precision holders, allowing the mill to be clamped securely in a variety of spindles. Its compact 0.16 mm cut length frees up clearance in tight cavities and reduces deflection during light finishing passes. No through-coolant channels means external flood or mist delivery is required.

Questions about this item

What shank size collet or holder do I need for the 0.20 mm diameter shank on this end mill?

The cutter has a 0.20 mm shank, so you need a collet, shrink-fit holder or hydraulic chuck that accepts that exact diameter.

Will the 0.16 mm length of cut reach the depth I need in my existing micro-machining setup?

The flute length is 0.16 mm, so it only engages material up to that depth per pass; plan step-downs accordingly.

How can I confirm the WXL coating is performing correctly after the first few passes?

Check for consistent chip colour, minimal flank wear under magnification, and stable cutting sound — signs the coating is reducing heat and adhesion.
