CARBIDE + Hard'X = hardness 1800 HV & 3500 HV, to machine steels over 1300 N/mm², treated steels up to 67 HRC, stainless steels, titanium alloys, hard bronzes, inconel, nimonic, waspaloy, hard cast irons and all other metals, thermoplastics, nylon, Pvc, laminated materials graphite, reinforced polymer with glass or carbon fibres, all ceramics, glass.

These short drills are specially designed to be used with revolver-handle pneumatic disconnectors.
Flated shanks with 60° taper for a good location in the disconnector.

The centering point grants perfect drilling without any deviating. Thanks to the special sharpening the first sheet will be bored without damage for the second one. Their design allows an excellent penetration, a high resistance to the wear and a great many regrinds.
These carbide spotweld drills are designed to machine the new very-high elastic limit sheet metal (VHEL).
