Parabolic flute design, effective in deep hole drilling of aluminum alloys and other low to medium tensile strength materials at higher feed rates. The 135° split point is self-centering and reduces thrust.
A dependable, general purpose drill designed to perform in a broad range of materials in the iron and steel families. Ideal for production, maintenance, or portible drilling jobs. Surface treated with abrasion-resistant black oxide.
Features heavy-duty construction and heat treated body for optimum wear resistance and support of the carbide tip. Used in the production of cast iron, non-ferrous metals, andmany composite materials such as hard rubber or copper alloys. NOT recommend for drilling steel.
Superhard titanium nitride surface treatment improves drill life, chip ejection, and productivity; decreases horsepower requirements. Ideal for hard metals, work hardened stainless and other difficult to drill materials.
Manufactured to National Aerospace Standard 907. Made of heat resistant cobalt, they display higher red hardness which permits speeds up to 30% greater than high speed steel drills and are especially effective in drilling tough, high tensile strength materials like PH stainless steel, inconel, and titanium. The 135° split point is self-centering and reduces thrust. Sizes smaller than 1/16" have the 118° standard point.
Manufactured to National Aerospace Standard 907, these drills are idaeal for portable or machine drilling of low tensile strength alloy materials. They have a black oxide surface treatment that is abrasion resistant, reduces ship welding and improves chip flow. the 135° split point is self-centering and reduces thrust. Sizes smaller than 1/16" have the 118° standard point.
