6pcs M35 HSS Countersink Chamfer Bits Set | 90° Deburring for Stainless Steel Iron Metal CE Certified

Clean metal edges every time. This 6-Piece M35 HSS Countersink and Chamfer Bit Set is specifically designed for metalworking — M35 cobalt HSS construction handles the hardness of stainless steel and iron that standard HSS bits cannot, delivering clean 90° countersinks, chamfers, and deburring on metal components.

Key Features

• M35 Cobalt HSS Construction — M35 grade cobalt-enhanced HSS provides superior hardness for cutting stainless steel and hard metals — significantly longer lasting than standard M2 HSS in metalworking applications.
• 90° Countersink Angle — Standard 90° angle for countersinking metric fasteners in metal fabrication and engineering applications.
• Deburring Capability — Chamfer geometry removes burrs and sharp edges from drilled holes in metal — produces safe, professional-quality hole finishes.
• Round Shank — Standard round shank fits all drill chucks without adapters.
• CE Certified — Safety and quality certified for professional metalworking use.
• 6-Piece Set — Multiple sizes in one set for different hole diameters and screw sizes.

Snagg It Tip

The key to clean countersinking in metal is speed and lubrication — use a slow to medium drill speed (300–600 RPM for stainless steel) with cutting oil or fluid applied to the bit. Running countersink bits dry in stainless steel causes work hardening that rapidly dulls the cutting edges. Always countersink to the correct depth — the screw head should sit flush with or fractionally below the metal surface for a clean, professional result.
