Premium TCT Hole Saw Kit for Hardened Metals

The GMTOOLS brand presents a comprehensive Cobalt Drill Bit Set and Hole Saw Kit. This versatile collection caters to a wide range of drilling and cutting needs.

The Cobalt Drill Bit Set features a set of high-performance drill bits made from cobalt alloy steel. These bits boast exceptional durability, wear-resistance, and superior cutting capabilities. They are ideal for drilling through steel plates, cast iron, stainless steel, and other metal materials.

The Hole Saw Kit, on the other hand, is designed to create precise, clean holes in a variety of materials. Crafted from tungsten carbide-tipped (TCT) cutters, these hole saws offer exceptional hardness, rust-resistance, and extended lifetime. The innovative three-blade design ensures smooth, efficient cutting with low consumption and high impact resistance.

The hole saws are available in a range of cutting diameters, from 5/8" (16mm) to 2-1/8" (53mm), catering to diverse application needs. The optimal cutting depth is 3mm for steel plates and 10mm for iron plates, though they can handle up to 20mm thickness with proper operation.

To ensure optimal performance and user safety, it is recommended to use a lubricant during high-speed drilling to prevent bit overheating. Operators should also wear protective eyewear and, when working face-up, a protective face shield is advised.

The cutter head's multi-tooth combination design, featuring inner, middle, and outer cutting edges, distributes the cutting force evenly, resulting in a smoother and faster drilling process. The tough tungsten carbide teeth extend across the inner and outer walls, reducing friction and increasing cutting speed.

The GMTOOLS Hole Saw Kit comes complete with 10 pilot drill bits and 2 hex keys, providing a comprehensive solution for a wide range of drilling and hole-cutting needs. It is suitable for use with hand-held electric drills, stand motor-driven drilling machines, and mobile ribbon-type magnetism drilling machines.

GMTOOLS stands behind the quality of its products, offering a 30-day money-back guarantee and a 100% satisfaction guarantee, ensuring a risk-free shopping experience for customers.
