Accupro 4-Flute AlTiN Coated Progressive Helix Single End Mill, 1/4″ Mill Dia., 1/4″ Shank Dia., 3/4″ LOC

Solid Micrograin Carbide
Stub, Regular & Long Lengths

Features:

• Progresses helix design changes from 35 at the tip to 60 at the shank, reducing vibration and chatter allowing for aggressive machining of stainless steels, steels, Inconels, cast iron and high-temperature alloys.
• Allows for increased feed rates by up to 50%, larger chip loads per tooth and extended tool life when compared to standard carbide end mills.

Tolerances Size Tolerance Shank Dia. All Sizes +.0001/-.0004″ Cutting Dia. All Sizes +.000/-.002″

Surface Treatments:

AlTiN (Aluminum Titanium Nitride)

• Recommended for difficult to machine materials.
• Used for aggressive machining of aircraft/aerospace materials, stainless steels, high alloy carbon steels, nickel based high-temperature alloys and titanium alloys. Also used in dry machining of cast irons, nodular iron and selected carbon steel.
• Extremely hard, wear resistant
• Provides increase of 75 to 100% in machining speeds vs. uncoated tools.
