Overview
TCT Hole Saw 21 mm with Carbide Tips Metal Drilling Crown with Titanium Guide Drill Cutting Depth 20 mm for Stainless Steel and Wood

The TCT hole saw is designed for drilling regular circular holes with a diameter of 21 mm in stainless steel, iron, and other metals. The cutting part is made of teeth with tips of carbide (tungsten carbide), which maintain sharpness even in harder materials. In the centre of the crown is a guide drill with a titanium coating, which determines the centre of the hole and stabilises the tool when starting the cut. The hole is cut out in one go without pre-drilling and gradually increasing the diameter. The crown is also usable for wood.

A diameter of 21 mm is suitable for working with metal cabinets, covers, brackets, and structures where you need to pass a pipe, cable, or install a connecting element. The teeth with alternating geometry of left, centre, and right edges divide the chip into smaller pieces, allowing the tool to cut more smoothly. Thanks to the cutting depth of 20 mm, the crown can penetrate sheets and walls of common profiles. The edge of the cut hole is clean and usually does not require significant additional finishing with a file or deburring tool.

Instead of drilling, mark and punch the spot with a centre punch to ensure the tip of the guide drill reliably catches. Hold the drill so that the crown is perpendicular to the material, and start at low speeds. Once the teeth have engaged all around, you can increase the pressure, but still evenly. Always securely clamp the workpiece and support thin sheet metal with a piece of wood to prevent it from bending during the crown's penetration.

When drilling steel and stainless steel, choose lower speeds and use cutting oil for cooling, which extends the life of the blades and helps remove chips from the cut. After use, clean the crown and store it in a dry environment. The guide drill is secured in the crown with a screw, so you can easily replace it after wear.

The TCT 21 mm hole saw is a reliable helper for installations, repairs, and workshop production where precise holes in metal are needed. The teeth made of tungsten carbide and the titanium guide drill allow for clean drilling even in stainless steel. You will use it for passing cables and pipes, for outlets, or for installing locks and fittings. The crown is clamped into the drill via a 10 mm shank. The total length of the crown is 80 mm.
