1/2" Shank Silver & Deming HSS Drill Bits - U.S.A.
Series Type 130AG MAGNUM Super Premium Drills outperform ordinary jobber drills by penetrating faster and lasting longer.
Additionally, Series Type 130AG MAGNUM Super Premium Drills offer:
?1/2" Reduced Shank to fit 1/2" Drill Chucks
?3 Flats ground on shank to give non-slipping positive chuck grip.
?Superior strength and durability provided by M7 molybdenum high speed steel.
?More holes per drill than ordinary twist drills, especially in cordless power tools.
?Functional black and gold surface treatment holds lubricants for smoother drilling and torsional strength.
?Meets MAS 907B aircraft specifications.
?135ø split point for fast penetration and accurate starting without a center punch. Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance. Body and clearance are gold surface treated for maximum lubricity.
?Heat treated at 2185øF and then nitro-carburized finished at 950øF to be measurably harder than high speed steel. Space age nitro-carburized steel withstands substantially higher drilling temperatures, while maintaining sharpness.
?Recommended for use in work hardening grades of stainless steel and other hard metal drilling applications.
?We have carried the 130AG series drill for the past 22 years and have yet to come across a better drill for the money.
