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.
