TG 90° Countersink, 6542 HSS, Round Shank, for Metal & Plastic, 6.3-35 mm

Key Features

• 6542 High-Speed Steel: Provides good hardness and wear resistance when machining compatible low-hardness metals and plastics.
• 90° Countersink Angle: Produces a 45° chamfer on each side of the hole entrance.
• Single-Flute Option: Supports smooth chip evacuation and controlled deburring, including accessible recessed and deeper hole entrances.
• Three-Flute Option: Provides efficient material removal when used on rigid, accurately aligned machining equipment.
• Five Cutter Diameters: Available in 6.3 mm, 10.4 mm, 12.4 mm, 30 mm and 35 mm sizes.

Available Variants

Variant Selection: Single-flute variants are recommended for soft materials, thin workpieces, controlled deburring and less rigid fixed machines. Three-flute variants are intended for efficient cutting on rigid, accurately aligned equipment such as machining centres.

Size Selection: The cutter diameter must be larger than the required finished chamfer diameter. The manufacturer recommends selecting a cutter approximately 1.5 times the required chamfer diameter.
