TCT Hole Saw for Metal 12 mm – Cemented Carbide – Koronet

The TCT hole saw by Koronet (in the photo a hole saw size 57 x 12 mm) is a precision tool designed to make holes in metal elements. The structure has been designed for stable, controlled operation in workshop and production conditions, where dimensional repeatability and hole edge quality are important.

The body of the hole saw is made of steel, while the cutting part is equipped with carbide (TCT) teeth, which allows for effective drilling in metals while maintaining the durability of the cutting edges.

The tool is equipped with a pilot drill bit, which is responsible for precise centering of the hole and a stable start of the drilling process.

TCT teeth – cutting resistance and stability

The use of cemented carbide (TCT) inserts provides:

• increased wear resistance,

• stable work in metal processing,

• Maintaining the geometry of the blades during operation.

This solution enables the production of holes with even edges and reduces tool degradation when working in harder metal materials.

Pilot drill – precise guidance

The hole saw has a centrally located pilot drill, the task of which is:

• accurate positioning of the tool,

• stable insertion of the hole saw into the material,

• Reducing the risk of displacement of the hole saw in the initial phase of operation.

The pilot drill is replaceable, which allows it to be disassembled and maintained.

Ejection holes – chip removal

The body of the hole saw is equipped with ejection holes that allow:

• effective removal of chips from the cutting zone,

• reduction of clogging of the tool,

• more stable drilling process.

This solution improves the control of the drilling process and affects the quality of the hole being made.

Hexagon shank (HEX) – secure attachment

The hexagon (HEX) grip used ensures:

• stable fit in the handle,

• Tool slip reduction

• transmission of torque in a controlled manner.

The hole saw is designed to work with drills and power tools equipped with a handle compatible with the HEX shank.

Application

The TCT hole saw for metal Koronet is designed for machining:

• structural steels,

• steel sheets,

• metal profiles,

• of metal pipes and components of standard thicknesses.

The tool ensures stable operation, control of the drilling process and repeatability of holes in workshop and production applications.
