M35 Cobalt High Speed Steel:Industry grade M35 high speed steel drill bit set, harder than 4241 HSS used in other similar drill bits set. These drill bits also contain 5% Cobalt, which increases wear-resistance and durability.
Fully Ground Process & 135° Split Point:Fully ground spiral groove design clears particles quickly, decreases friction and heat for a faster and cooler drilling performance. 135° split point with straight shank prevents walking and makes drilling precise and faster. No center punch is needed.

1.High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance.  Double Ended Drill Bits 5% Cobalt M35 Hss Metal Twist Rivet 4.2mm For Iron Sheet
2.No center punch is needed-the aggressive 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not “walk” or “wander”.
3.Precision ground point, flutes, body, clearance and drill diameter for the ultimate in accuracy and performance.
4.Ground flutes provide fast chip removal to maximize accuracy and efficiency along the full working surface of the bit.
5.The double ended design doubles the life of the drill bit.

We are a Manufacturer and Exporter of Double Ended Drills in India, having flute and split point on both ends and also have solid center shank for chucking. Double-ended Drills can drill double holes more than a single-end drill, reducing the change over time, inventory, and overall cost. These bits are used to drill thin metal sheets. The 2-in-1 drill offers superior cutting performance in various metals, including steel, aluminum, and stainless steel.  Double-Ended Drill Bits are available in a limited range of imperial sizes; number sizes are perfect for installing and removing rivets.

Our tools are made from high-quality raw materials, ensuring world-class quality and the best performance. We provide all materials and size ranges based on the customer’s specific drawings and sizes. The cutters are exported to various countries worldwide. HSS 6542 Double Ended Drill Bits Fully Ground
