Subland drills

Subland drill bits are specially designed tools that combine drilling and countersinking in a single step. This design enables efficient hole creation with precise diameters while simultaneously countersinking for screws with various head types, improving productivity and accuracy. Read More

Features and Benefits of Subland Drill Bits

Made from high-speed steel with cobalt (HSS-Co.), these drill bits offer excellent wear and heat resistance, making them ideal for working with harder materials. They are suitable for drilling into alloyed and unalloyed steel, cast iron, copper, aluminum, brass, bronze, stainless steel (V2A, V4A), plastics, plywood, and wood.

Available Types of Subland Drill Bits

• Subland drill bits 90°, HSS-Co. – Ideal for creating holes for countersunk screws.
• Subland drill bits 90°, HSS-Co., long – Allows drilling and countersinking in hard-to-reach areas or thicker materials.
• Subland drill bits 180°, HSS-Co. – Designed for screws with cylindrical heads, providing precise drilling and countersinking in a single step.

Extending Tool Life

For easier drilling and longer tool life, we recommend using cutting oil, cutting and drilling spray, or cutting paste. These products reduce friction, prevent overheating, and enhance tool longevity.
