## Long description

The Countersink Set for Metal TOYA STHOR 6-piece 6.3–20.5 mm is a selection of six solid countersink cutters designed for deburring, chamfering, and enlarging holes in steel and similar ferrous materials. Supplied as a matched set, the cutters cover a range of diameters from 6.3 mm up to 20.5 mm so you can choose the correct size for through-holes, clearance holes, and simple chamfering operations. The set is intended for use with standard electric drills and drill presses in workshops, maintenance, and fabrication environments.
Advantages
The set provides a compact assortment of sizes that reduces the need to stop work for tool changes. Each cutter is shaped to deliver clean edges and consistent countersink geometry, helping to improve fit and finish on metal parts. The cutters are suitable for use on steel and other ferrous materials and are compatible with common drill chucks, making them versatile for both handheld and machine-mounted operations.
Suitable for
Deburring and removing sharp edges from drilled holes in steel
Creating clearance or countersunk holes for fasteners
Enlarging existing holes to the specified diameter range
General metal workshop maintenance and fabrication tasks
When it may not be suitable
The set is intended for use on steel and other ferrous materials; it is not specifically optimized for non-ferrous metals such as aluminum, brass, or for composite materials where different cutter geometries or coatings may be preferable. It is not a multi-purpose hole saw and is not designed for cutting large-diameter holes beyond the maximum size in the set.
Key specifications
Number of pieces: 6 cutters
Diameter range: 6.3 mm to 20.5 mm
Intended material: steel and other ferrous metals
Compatible mounting: standard drill chucks for drills and drill presses
Primary functions: countersinking, deburring, hole enlargement
How to use
Select the cutter closest to the desired finished diameter, secure it in the drill chuck, and set an appropriate spindle speed for the material being worked. Use steady, moderate feed pressure and keep the tool aligned with the hole axis to produce an even chamfer or bore. Retract periodically to clear swarf and prevent overheating. For consistent results, clamp the workpiece and use a drill press where possible; when using a handheld drill, ensure a firm grip and controlled movement.
What to consider before purchase
Confirm the diameter range (6.3–20.5 mm) matches your application needs
Verify suitability for the specific metal you will work with (primarily steel and ferrous alloys)
Ensure your drill or drill press accepts the cutter shank and provides sufficient speed and torque
Consider using cutting fluid for improved tool life and finish when working with steel
Usage recommendations
Use moderate speeds and cutting fluid when countersinking steel to prolong cutter life and improve surface finish. Clamp the workpiece securely and align the tool to the hole axis; for repeatable results, prefer a drill press over handheld drilling.
