Irwin® Mechanics Drill, 7/16 in, 4-9/16 in Overall Length

Description

Irwin® Mechanics Drill, Fractional, Series: 305, 7/16 in Drill - Fraction, 0.4375 in Drill - Decimal Inch, 4-9/16 in Overall Length, 2-5/8 in Cutting Depth, 2 Flutes, Spiral Flute, 2-5/8 in Flute Length, 7/16 in Shank, Cylindrical Shank, 135 deg Point, Split Point, Left Hand Cutting Direction, M42 HSS-E-Co Cutting Edge, Cobalt/M42 HSS-E, Gold Oxide, Applicable Materials: Wood/Metal/Plastic

Features:

• Constructed of M-42 8 percent cobalt high speed steel for super abrasive resistance in tough metals
• Heavy duty spiral flute design produces faster chip ejection
• Shorter cutting lips reduce torque for drilling in high tensile strength materials
• 135 deg split point reduces feed pressure for easier penetration without work hardening
• Ideal for use with screw extractors, made for drilling into hardened steel bolts for creating pilot hole
• 8% cobalt alloyed for higher heat and abrasion resistance
• Shorter drill for additional strength
• Drill into fasteners without tightening them
• Can often remove broken fasteners without an extractor
• Heavy duty web construction for strength and durability

Applications:

For tough metal drilling applications
