Popular RUSHMORE USA 102894 3/16″ Size, 5/8″ LOC, 4 Flute, AlTiN Solid Carbide Square End Mill

Solid Carbide AlTiN-coated Finishing End Mill for General Machining Applications. Presented here are square nose, right-hand single-end mills from Rushmore. The product is offered in a 4-flute, center-cutting, right-hand spiral design with a lower helix angle of 30°. It comes in 22 different fractional sizes ranging from 1/32″ to 1″ with a shank diameter of 1/8″, 3/16″, 1/4″. The assortments are made from premium submicron carbide with 10% cobalt. The AlTiN coating on the cutting edges offer good thermal stability for increased speeds and feeds. It results in excellent heat resistance, good lubricity, better finishes and prolongs tool life. Square end mills are generally applied in slotting, profiling, peripheral, helical, ramping, and plunge cutting. Rushmore’s solid carbide finishing mills are designed & employed in rough and general machining applications of high-temperature exotic materials and high cobalt and high nickel alloys including 200 & 300 series stainless steels. The lower helix angle wraps tool material slowly and is used for aggressive cuts. Rushmore USA Tools offers quality affordable American-made tooling with the superior speed and feed that your applications require. Rushmore’s end mills are perfect for all aerospace, medical, automotive, or production machining solutions.

Benefits

• Multi-layer coating used in wet, semi-dry to dry cutting of most steels and highly abrasive materials.
• Provides good thermal stability for increased speeds and feeds that offers excellent heat resistance, good lubricity, better finishes and prolongs tool life.

Applications

This Rushmore USA 3/16″ solid carbide 4 flute corner radius end mill with no corner radius carries a AlTiN coating, set up for general-purpose mixed workpiece milling. A 30° slow helix reduces lifting under heavier engagement, smoothing the resulting surface. A longer overall length adds reach for deeper features.

Features

• Made from premium submicron carbide with 10% cobalt.
