TCT Drill Bit 75 mm for Metal Hole Saw with Carbide Teeth and Titanium Guide Drill Bit Cutting Depth 20 mm for Stainless Steel, Steel and Wood
You already have the maximum available quantity in your cart.
The TCT drill bit cuts a circular hole in metal with a diameter of 75 mm in a single working step. The teeth of the hole saw are fitted with tungsten carbide cutting edges, capable of handling stainless steel, iron, and other metal materials. The guide drill bit with a titanium coating in the centre of the saw drills the centre of the hole and keeps the tool straight throughout the drilling process. Thus, there is no need to gradually enlarge the large hole. The saw is also suitable for drilling into wood.
A diameter of 75 mm is useful for passing thicker pipes and tubing through sheet metal walls, for installing large grommets, or for modifying metal cabinets, covers, and technical panels. The teeth feature an alternating geometry, with left, centre, and right cutting edges arranged around the circumference. This design breaks the chips into smaller pieces, resulting in reduced vibrations during drilling. The useful cutting depth of 20 mm accommodates sheets, strips, and walls of steel profiles.
Before drilling, mark the centre of the hole and punch it with a centre punch to prevent the guide drill from slipping on smooth material. Secure the workpiece firmly, preferably in a vice or with clamps to a workbench. Hold the saw perpendicular to the surface and start with slow speeds until the teeth evenly engage around the circumference. Then apply a steady and moderate pressure. Support thin sheet metal with a board to prevent it from bending around the hole.

The 75 mm diameter hole saw has a high cutting speed at the circumference, so when drilling into steel and stainless steel, set low speeds and use cutting oil or other cooling methods. Allow the tool to cool between holes. After use, clean the saw of chips and store it in a dry place. The guide drill bit is held in the body of the saw by a screw, allowing for replacement after wear.
The TCT 75 mm drill bit is an excellent tool for craftsmen and DIY enthusiasts who need large, clean, and precise holes in sheet metal and steel parts. The carbide cutting edges also cut through stainless steel, and the spring on the guide drill bit ejects the cut material from the saw once the hole is completed. It is clamped onto a 10 mm shank for use with standard handheld drills as well as pillar drills. The total length of the saw is 80 mm. It is suitable for plumbing, electrical, and locksmithing work.
