Champion Drill Bit Set TWISTER-XL5 1/16 to 1/2 Inch Brute Platinum (29 Piece Jobber HSS 135 Split Point NoMo Nitride Stainless Steel Metal Drilling)

Champion Cutting Tool TWISTER-XL5 Brute Platinum 29-Piece HSS Drill Bit Set

The Champion Cutting Tool TWISTER-XL5 29-piece Brute Platinum jobber length drill bit set delivers rapid hole penetration and fracture-resistant metal drilling across 1/16-inch to 1/2-inch diameters in fractional 1/64-inch increments. Precision-manufactured in the USA from premium high-speed steel with a proprietary NoMo (Nitride on Margin Only) surface treatment, these bits combine extreme cutting edge hardness with torsional flexibility to prevent catastrophic snapping in hard alloys. Engineered with a self-centering 135-degree split point tip and heavy-duty tapered web geometry, this set eliminates bit walking and center punching while drilling through stainless steel plate, titanium, structural carbon steel, and cast iron in drill presses, CNC centers, and handheld power drills.

Best Used For:

• Stainless Steel and Hard Alloy Fabrication: Penetrating work-hardening 304/316 stainless steel, titanium, and armor plate without premature cutting edge glazing or tool snapping.
• Structural Steel Erection and Ironworking: Drilling accurate, clean clearance bolt holes through heavy steel flanges, channel iron, and drop forgings on handheld jobsite drills.
• Machining and Drill Press Operations: Performing continuous, high-feed production drilling in CNC centers and stationary drill presses with self-centering accuracy.

Key Performance & Safety Features

• 135-Degree Self-Centering Split Point: Starts cutting immediately on contact to eliminate drill bit walking without pre-drilling pilot holes or center punch indents.
• Proprietary NoMo Nitride Treatment: Hardens the drill margins to maximize wear resistance and hole yield while keeping the tool core flexible under torsional torque.
• Engineered Tapered Web Core: Thickened central flute web provides increased structural rigidity and optimal chip evacuation under heavy mechanical downforce.
• Cobalt Alternative Flexibility: Delivers 2X faster penetration and 3X longer operational life than cobalt bits without the brittle fractures common in handheld drilling.
• Fractional 1/64-Inch Step Index: Comprehensive 29-piece progression ensures exact dimensional matching for fractional tap pilots, reamers, and bolt clearance holes.
• Water-Resistant Round Index Case: Impact-resistant Twister storage cylinder protects cutting lips from jobsite moisture, rain, and abrasive metal dust.

What's Included

• (29) Champion Brute Platinum XL5 Jobber Length Drill Bits (1/16" to 1/2" in 1/64" increments)
• (1) Heavy-Duty Water-Resistant Indexed Cylindrical Storage Case

Technical Specifications

Pro-Tip: Apply steady feed pressure and a quality sulfur-based cutting fluid when drilling stainless steel; keeping the cutting speed low prevents heat buildup and stops the alloy from work-hardening.
