Jobber Length Drills

Heavy-duty construction for drilling in tough, high-tensile and work-hardening materials under extreme operating conditions. Manufactured from cobalt high-speed steel, increasing hot hardness and extending drill wear life. 135° P3 split point is self-centering for reduced thrust and easier penetration. Sizes smaller than .0625" do not have split point. Metric sizes are manufactured to DIN 338 OAL and flute length specifications. Straw finish adds lubricity and easily identifies cobalt drills. For drilling in stainless steel, tool steel, alloy steel and titanium. Made In USA. Pack Of ...

Carbide Tipped Jobbers Drill Applications: Designed especially for use on cast iron and non-ferrous materials (not on hardened steel) Features: Right hand spiral, right hand cut, heavy duty high speed steel body The length of each drill is variable and is determined by the specific drill diameter offering the best balance between overall drill rigidity and depth capacity for each drill diameter Benefits: Provides excellent wear resistance 2 to 2.5 times faster speed compared to standard high speed steel yields faster holes with better hole finish

TiN (Titanium Nitride)-Tipped drills increases lubricity and heat resistant. Same benefits of TiN (Titanium Nitride) coated at a fraction of the cost. Manufactured from high-speed steel. 135° split point prevents walking, which produces a better quality hole. For drilling into mild steels or soft metals, like aluminum, copper, brass, bronze and non-ferrous materials. Pack Of 12. 30 Day Warranty.

General Application Drills geometry for drilling in a wide range of operating conditions and materials. Manufactured from premium high-speed steel. 118° point. The most popular drill for General Application Drills applications. Metric sizes are manufactured to DIN 338 specifications. Black oxide surface finish increases wear resistance and adds lubricity, improving chip flow. For drilling in carbon steel and cast iron. Made In USA. Pack Of 12. 30 Day Warranty.

Fast Spiral Drill Bit A fast spiral drill bit is used in high feed rate applications under low spindle speeds, where removal of a large volume of chips is required. Use for drilling soft materials such as Aluminum. Applications: For drilling operations in low tensile strength, softer materials that may pose problems with chip removal Typically the materials drilled with these drills are softer ferrous metals and alloys, such as soft steels and soft cast iron and soft non-ferrous metals and alloys, such as aluminum, magnesium, copper and zinc alloys The drills feature a combination of fast ...
