Best Spiral Reduced Shank Drill Bits in 2026

High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance

Gold and black surface treated for use in stainless steel and other hard metal drilling

Round shanks allow use with a wide variety of toolholding systems

Accuracy & Longevity - 135 degree split point starts drilling immediately requires less force and eliminates “walking” across the working surface. Tapered web provides strength, durability, and reduces breakage.

Three-Flat Design - Three flats on shank eliminate bit spinning in chuck. Our proprietary parabolic flute design brings optimal chip removal which reduces heat build-up.

Wide Range of Uses - Drill bits are built for general purpose applications, such as steel/copper/aluminum/zinc alloy/wood/plastics. Also, it's ideal for DIY projects and home maintenance. Durable and reliable quality.

Durable Construction - HSS material with black and gold coating increases lubricity, provides corrosion protection, and increases durability. Ensures longer tool life in multiple working conditions. Tapered web provides strength, durability and reduces breakage.

No Center Punch is Needed - 135° split point design for fast penetration with less pressure. Twist drill bit kit will not "Walk" or "Wander".

Parabolic Flute - Parabolic flute for better chip removal and reduced heat build-up.
