Maykestag HSS-Co5 90° countersink 40mm DIN 335 D with MK3 Morse taper
Professional 40mm countersink manufactured from HSS-Co5, featuring a 90°
countersinking angle, three cutting edges and an MK3 Morse taper shank for
precise and efficient countersinking of drilled holes.
The Maykestag Form D countersink is a precision HSS-Co5 cutting tool designed
for producing clean 90° countersinks in pre-drilled holes. Its three-flute
cutting geometry provides balanced cutting action and efficient chip
evacuation, while the MK3 Morse taper shank provides a secure and rigid
connection to suitable machine toolholders. With a 40mm countersinking
diameter and 140mm overall length, this countersink is suited to professional
workshop and production applications where accurate, consistent countersinking
is required.
What is a countersink? A countersink is a cutting tool used
to create a conical recess around the opening of a drilled hole.
Countersinking allows the head of a suitable countersunk screw or fastener to
sit flush or below the surrounding surface. The 90° geometry of this
Maykestag tool is designed for producing standard 90° countersinks.
