Kennametal 1199424 Jobber Length Drill Bit, 11.50 mm (0.4528) Diameter, 130 deg, Solid Carbide, Bright / Uncoated Finish, 118.00 mm

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.
• TiAlN-Coated KC7210 Grade for higher wear resistance at elevated speeds.
• Uncoated K10 Grade helps to prevent built-up edge in drilling aluminum and high-temp alloys.
• Jobber Length Drill Bit: 11.50 mm (0.4528) Dia, 130 deg, Solid Carbide
• Bright/Uncoated Finish, 118.00 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.
