Straight Shank Jobber Drills, HSS, Heavy Duty, TiN Coated, Fractional Sizes

• Proven Industrial Quality and Consistency
• High Speed Steel
• Heavy Duty Construction with 135° split point for rugged applications that do NOT require the heat resist properties of Cobalt
• An economical alternative to Cobalt drills for steel applications 250 Brinell or more in hardness.
• Spilt Point provides reduced trust and increases ease of starting on center
• Titanium Nitride (TiN) Coating provides increase surface hardness, lubricity and wear resistance resulting in increase tool life
• When using Titanium Nitride (TiN) Coated drills increase SPEED by 25-30% in Carbon Steels, 20%-25% in Alloyed Steels, Die Steels, and Stainless Steels and by 25% for Cast Irons. Increase feed rates by 10% for drilling diameters 3 X D and less
