Terminator Carbide Straight Flute Drill Bits – METRIC

METRIC Carbide Straight Flute Drill Bits for Work hardened Steels 42- 65 Rockwell

Made in USA

Terminator series

Engineered to deliver reamer-quality finishes in work-hardened and high-alloy steels.

Superior oxidation resistance provides unparalleled performance in high temperature machining.
Micro-hardness 3600 Vickers. Thermal Stability (750 deg. C or 1562 deg. F) Coefficient of Friction .45

These are the best drill bits you can use for drilling out broken bolts and fasteners. Also great for drilling out broken-off easy outs! When only the best will do.0

Made in USA

Carbide straight flute drill bits are engineered for maximum rigidity and control when drilling extremely hard or work-hardened materials. The straight flute geometry reduces deflection and chatter, maintains cutting edge strength, and prevents grabbing or walking when drilling broken bolts, hardened fasteners, and high-alloy steels—delivering reliable performance where HSS and cobalt drills fail.

Why These Win

• Sub-micron solid carbide construction for extreme wear resistance
• Straight flute design = maximum rigidity, zero grabbing
• Reamer-quality hole finish in hardened materials
• 140° split point for accurate starts without wandering
• Made in USA – built for real machining, not disposable use

Built for Extreme Materials

Designed to cut:

• Work-hardened steels (42–65 Rc)
• Stainless steel weldments
• Chrome, nickel, and heat-resistant alloys
• Titanium and high-strength alloys
• Broken bolts, studs, and fasteners
• Seized or snapped easy-outs / extractors

Performance Specs

• Micro-hardness: 3600 Vickers
• Thermal Stability: 750°C (1562°F)
• Coefficient of Friction: 0.45
• Oxidation Resistance: Built for high-temperature cutting environments

Where These Dominate

When you’re drilling:

• Broken exhaust manifold bolts
• Hardened studs that laugh at cobalt
• Snapped extractors (easy-outs)
• Welded or work-hardened material

This is the tool you reach for when nothing else is working.
