Kennametal 1790924 Jobber Length Drill Bit, 0.3566" Dia, 130 deg, Solid Carbide

TiAlN Finish, 4.0600" OAL, Right Hand Cut, Regular Spiral Flute, Straight Shank.

Composition: Uncoated, highly wear-resistant fine-grain carbide with enhanced hot hardness properties.

Application: Best suited for dry and external flood coolant applications in aerospace materials like high-temperature resistant materials and wrought aluminum alloys. Due to its high wear-resistance, this grade is also applicable for cast iron machining at low to medium speeds.

Features:

• TF type drills without through coolant for high metal removal rates and excellent hole quality
• Material-specific SC drill with three cutting edges for higher feed rates than with two-edged drills.
• Three spacious flutes for rapid chip evacuation.
• Three-margin lands deliver better hole quality and straightness than two-flute drills.
