Drill Blanks

Parabolic flute disperses chips away from the cutting edges more rapidly and increasing coolant flow. Exceptional for deep-hole drilling. Manufactured from high-speed steel. Aerospace-style 135° split point is self-centering, reducing walking. Faster penetration rates than conventional HSS heavy duty jobber drills. Bright finishes. For drilling in low carbon steel, soft alloy steel, non-ferrous materials and aluminum with TiCN as a modification. Made In USA. Pack Of 12. 30 Day Warranty.

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

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 ...

Bright Finish Jobbers Drill Applications: Polished drills help increase chip flow in soft materials Features: Standard two flute design with standard spiral, helical flutes Straight shanks correspond to the drill diameter 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 Technical Data: Manufactured from high speed steel Cylindrically ground. From solid Normal duty, general purpose drills 118° point angle and standard web thickness
