Product Overview

Maximize efficiency in your heavy-duty drilling operations with our industrial series of Rolled Taper Shank Twist Drill Bits. Manufactured from high-grade HSS 6542 (M2 equivalent High-Speed Steel), these bits are designed to deliver reliable performance, high wear resistance, and excellent "red hardness" for demanding metalworking environments.

The roll-forging process used to create these drills preserves the inherent grain structure of the steel, offering superior toughness and resistance to snapping compared to standard ground drills in heavy-feed applications. Featuring a standard Morse Taper (MT) shank, these bits ensure a rigid, zero-slip connection in lathe tailstocks, radial arm drills, and magnetic drilling machines, allowing for maximum torque transfer.

Available in a comprehensive metric range from 13mm to 23mm diameter, these drills are the workhorse solution for fabricators and machine shops requiring reliable hole-making in mild steel, cast iron, aluminum, and various alloys.


Key Features & Benefits


     High-Speed Steel 6542 Construction: Utilizes premium M2-grade HSS for an optimal balance of hardness, toughness, and heat resistance during continuous drilling.

     Roll-Forged Process: The rolling manufacturing technique enhances the structural integrity of the bit, providing excellent durability for general-purpose industrial use.

     Secure Morse Taper Shank: The precision tapered shank locks firmly into machine spindles (e.g., MT2, MT3 based on size), preventing slippage under high-torque loads.

     Optimized for Chip Evacuation: The standard helical flute design efficiently clears heavy chips from deep holes, reducing heat buildup.

     Versatile Surface Finishes:

            Nitrided (Black): Increases surface hardness and lubricant retention (as seen in the product image).

            Polished (Bright): For clean cutting in softer materials.

            Black & White: A dual finish combining groove capability with land wear resistance.


Ideal Applications


     Heavy-duty fabrication shops.

     Industrial maintenance and repair.

     Machining steel plates, I-beams, and castings.

     Drilling operations on lathes and radial arm drills.
