Dormer PFX A941 17/64 AICrN Coated Cobalt Taper Length Parabolic Flute Drill 130 Degree Notched Point 0635940

The Dormer A940 & A941 Long-Length Drill Bit Is A 130-Degree, PFX Point, Round Shank Drill Bit Made Of Cobalt Steel. It Can Drill Holes Up To 10 Times The Diameter Of The Drill. The Shank Diameter Is The Same As The Drill Size. This Drill Has a Type W Flute Form, With a Fast Helix Angle Of 35 To 45 Degrees, and Are Most Suitable For Drilling Into Steel, Stainless Steel, Titanium, Nickel, and Alloyed Aluminum. This Design Allows For Single-Pass Drilling, Which Helps Eliminate The Need For Pecking In Up To 10 Times The Drill Diameter Deep Holes, Thus Offering Improved Efficiency and Increased Productivity. The Long Length Offers More Reach and Depth Than a Jobber Length Drill Bit. The Composition of HSS and Cobalt is a Good Combination Of Toughness and Hardness Needed For Deep Hole Drilling. The Parabolic Design, Combined With a Parallel Thinned Web, Allows For Smooth and Efficient Chip Removal. With Proper Cutting Conditions And Rigid Machine Setup, Holes To H10 Tolerance Can Consistently Be Achieved. The Uncoated Finish Of The A940 Helps Increase Chip Flow In Soft Materials and the A941 AICrN Coating Increases Lubricity and Wear Resistance Which Improves Tool Life. Spiral Flutes Act As a Passageway For Chip Removal and for Coolant to Enter The Hole. A Right-Hand Twist Brings Chips Up and Away From The Cutting Edge. Made of Cobalt Steel, Which is Many Times Harder and Stiffer Than HSS, will Hold an Edge Longer, and Will Deflect Less Than HSS. It is Also More Heat Resistant Than High Speed Steel. These Qualities Allow it to Run At Higher Speeds and Feeds. They Are Made to ANSI and DIN Standards, Which Help Ensure That Drill Bits Around The World Conform To The Same Specifications.
