Kennametal 1153171 Jobber Length Drill Bit, 7/32" (0.2188) Diameter, 130 deg, Solid Carbide

Features:

• Jobber Length Drill Bit: 7/32" (0.2188) Dia, 130 deg, Solid Carbide
• Bright / Uncoated Finish, 3.2300" OAL, Right Hand Cut, Helical Flute, Straight Shank, Series K105
• TF type drill 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 provide rapid chip evacuation.
• Three-margin lands deliver better hole quality and straightness than two-flute drills.
• TiAlN-coated KC7210 grade provides higher wear resistance at elevated speeds.
• Uncoated K10 grade helps prevent built-up edge in drilling aluminum and high-temperature alloys.

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.
