1/16″ End Mill – Corner Rounding, High Speed Steel – Right Hand Cut, LittleMachineShop.com (5137)

Description

Product Overview

The 1/16 inch high speed steel (HSS) end mill with corner rounding is engineered to deliver consistent, high‑quality cuts in a variety of materials. Its 3/8 inch shank provides a solid, rigid connection to the spindle, while the 7/16 inch head diameter ensures stability during high‑speed operation. The overall length of 2.5 inches gives ample reach for deep pockets and tight radii, and the form‑relieved geometry reduces friction, extending tool life and minimizing chip buildup. Constructed from premium HSS, the cutter maintains hardness at elevated temperatures, allowing it to perform reliably in demanding machining environments. The right‑hand cut orientation matches standard CNC and manual milling setups, making it a versatile addition to any tool chest.

Usage

This end mill excels in applications that require precise interior corner machining, such as creating fillets, slots, and pockets in aluminum, steel, brass, and engineered plastics. It is particularly well‑suited for hobbyist projects, prototype development, and small‑batch production where tight tolerances are essential. The cutter can be used on CNC milling machines, manual column mills, and even on rotary tools with appropriate collet adapters. Its compact size allows it to reach into confined spaces, making it ideal for aerospace component machining, automotive part refurbishment, and custom fixture fabrication. Users should select appropriate spindle speeds and feed rates based on material hardness to maximize performance and tool longevity.

FAQ

What materials can this end mill cut?

The cutter is suitable for non‑ferrous metals such as aluminum, brass, and copper, as well as ferrous steels, stainless steels, and engineering plastics like Delrin and Acetal.

What spindle speed is recommended?

For aluminum, use 12,000–15,000 RPM; for steel, 8,000–10,000 RPM; for plastics, 10,000–12,000 RPM. Adjust feed rates accordingly to maintain a smooth chip flow.

Is this tool compatible with CNC machines?

Yes, the right‑hand cut orientation and standard shank size make it compatible with most CNC milling centers and manual mills equipped with a 3/8 inch collet.

How do I maintain the end mill?

After each use, clean the cutting edges with a solvent, inspect for wear, and store in a dry environment. Periodic sharpening can restore cutting performance if needed.
