Countersinks otherwise as standard 3-Flute series 456B, but in HSSE+Cobalt material. Wide chip spaces allow ease of
working in some non-metallic materials. Can be used on the production line or in hand-directed tools for maintenance
and site work. They have radial relief of the teeth which reduces rubbing and permits fast cutting rates. 3-flute style aids
centrality and easy starting.
Available routinely in metric size and in 90° (DIN335) only.
Limited stocks of 60° angle are currently also held. Other angles such as 82°, 100° and 120° are available, as
are other combinations which may be supplied to special order. In case of special manufacture, the quantity
ordered will determine the unit price.
PLEASE NOTE THAT COUNTERSINKS are suitable for sinking a range of diameters, so that the large (outside) tool diameter
is rarely critical, and therefore near fractional and metric sizes may be used interchangeably. This increases the range of options.
