Kennametal 1790880 Jobber Length Drill Bit, 4.66 mm (0.1835) Dia, 130 deg, Solid Carbide

TiAlN Finish, 73.91 mm 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 in short chipping materials such as gray cast iron, ductile iron, and aluminum, as well as in short-hole titanium applications.
• 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.
