3/16-inch cobalt end mill

This 3/16-inch diameter cobalt end mill is a general-purpose cutting tool designed for milling operations. It features a square end style with four flutes and a single-end configuration. The bright uncoated finish suits standard machining tasks in a workshop environment.

Sustained cutting with 30-degree helix

The 30-degree helix angle promotes steady chip evacuation during extended milling passes rather than only short engagements. Four flutes distribute the cutting load evenly, which helps maintain consistent surface quality when the tool remains in the cut for longer periods. Cobalt construction resists heat buildup that can degrade edge retention over time.

Uncoated bright finish constraints

The bright uncoated surface lacks the lubricity and heat barrier of modern coatings, so it reaches its practical limit sooner in abrasive or high-temperature alloys. Users working with sticky materials or very high cutting speeds will find tool life shorter than with coated alternatives. The sharp .000-inch corner radius leaves no margin for corner-radius programming.

Questions about this item

How much heat does the 3/16-inch cobalt end mill generate during continuous finishing passes?

Cobalt steel resists heat build-up better than standard high-speed steel, so the tool stays harder at elevated temperatures during extended finishing cuts.

What holder or collet do I need for the 3/8-inch shank?

A standard 3/8-inch ER collet, Weldon flat holder, or mill chuck with a matching bore will secure the straight shank without adapters.

Will this 30-degree helix, bright-finish cutter work in my older manual knee mill?

Yes, the right-hand 30-degree helix and uncoated surface are well suited to conventional manual machines running at moderate spindle speeds.
