Specifications:
1/4" cutting diameter x 1/4" shank diameter x 3/4" length of cut x 2-1/2" overall length
3 Flute, 45° Helix, Solid Carbide End Mill, ZrN Coated, Square End

Package Included:
1pc 1/4" 3 Flute 45° Helix Carbide End Mill

Features:
ZrN Coating: ZrN (Zirconium Nitride) coating provides high hardness, low coefficient of friction, improved wear resistance and good thermal stability. Micro grain carbide mill bits offers enhanced rigidity and excellent heat resistance.
3 flute and 45-degree helix allow harmonic balance at high speed condition and smooth cutting.
Material: SEFHLI end mill is made from solid carbide, which gives it exceptional toughness, durability, and machinability and offer long tool life and faster cutting speeds than other substrates.
Precision ground using the highest quality grinding wheels. High strength and hardness, abrasion resistant, practical, easy to use and durable in use.

Application:
Application: High velocity milling of Aluminum and Copper.
