Description

HSS countersink set 90° ELORA 1359-S contains six tools for chamfering and deburring drilled holes in metal. Each countersink is made from high-speed steel. The 90° angle suits countersunk screws and removes sharp edges. Three cutting flutes ensure stable material removal. Cylindrical shanks fit standard drill chucks. The set complies with DIN 335 C.

Diameters range from 6.3 to 20.5 mm. This span covers common hole sizes in mechanical engineering. Users can prepare countersunk screw seats or clean burrs around hole edges. The compact ABS case keeps tools organized. Each slot is marked with the corresponding diameter.

Construction and Material of the HSS Countersink Set 90°

High-Speed Steel Cutting Edges

All six countersinks are manufactured from HSS. This material maintains hardness at elevated temperatures. The 90° point angle is ground precisely. Three flutes distribute cutting forces evenly. Cylindrical shanks measure consistently for secure clamping. Each tool is heat-treated to resist wear during repeated use.

  • Material: high-speed steel (HSS)
  • Point angle: 90°
  • Number of flutes: 3
  • Shank type: cylindrical, straight
  • Standard: DIN 335 C

The three-flute design reduces vibration compared to single-edge tools. Chips evacuate through the flutes. The cylindrical shank allows quick changes in hand drills or drill presses. DIN 335 C specifies dimensional tolerances and angle accuracy.

ABS Storage Case

The hinged case is molded from ABS plastic. It features six labeled recesses. Each recess holds one countersink securely. A snap-lock closure prevents accidental opening. The case protects cutting edges during transport. Dimensions are compact for toolbox storage. Total weight including tools is 296 grams.

  • Case material: ABS plastic
  • Closure: snap-lock
  • Slot labeling: diameter markings
  • Total weight: 296 g

Labeled slots speed tool selection on the workbench. The snap lock withstands repeated opening cycles. ABS resists impact and chemical exposure. The case fits standard tool drawers and portable kits.

Common Applications

This countersink set suits machine shops, maintenance workshops, and automotive garages. Operators use it to chamfer holes before installing flat-head screws. The 90° angle matches ISO and DIN countersunk screw profiles. Deburring drilled holes improves part finish and safety. The range of diameters handles pilot holes from 3 mm to over 12 mm. Metalworkers apply these tools to steel, aluminum, brass, and cast iron. Hand drills and drill presses both accept the cylindrical shanks.

ELORA designates this set as model 1359-S. It conforms to DIN 335 C for form C countersinks. The standard defines the 90° included angle and shank diameter tolerances. Each tool is ground to maintain concentricity. HSS composition provides edge retention across ferrous and non-ferrous metals. The ABS case dimensions allow stacking in tool cabinets. Users should store the set in a dry environment to prevent surface oxidation.
