About this item

This set of 5 square end mills (ISE1/4 4T, 1/4" 4-flute) is made from micrograin carbide for toughness and long tool life. The AlTiBN coating gives it strong resistance to heat buildup during cutting, outperforming common TiAlN, TiN, or TiCN coated bits. It's rated for carbon steel, alloy steel, pre-hardened steel, hardened steel, and cast iron, with tight ±0.02mm precision for clean finishes. A solid pick for CNC milling work, whether you're a DIYer or running a shop.

• 4-flute square end mill, 1/4" shank size (ISE1/4 4T), pack of 5
• Built from micrograin carbide for strong, durable cutting edges
• AlTiBN coating handles high heat better than TiAlN, TiN, or TiCN coatings
