Replaces worn or incorrect angle countersinks
Upgrade when existing bits no longer cut clean 100-degree profiles in steel or composite materials. The High Speed Steel construction resists heat during repetitive powder actuated fastening cycles. Not suited for buyers needing larger body diameters or different included angles for non-standard fastener heads. Machine operators requiring carbide tips for abrasive alloys should select a different tool.

Questions about this item
What shank diameter fits the 3/8 in body on the 56878 countersink?
The 3/8 in body is the cutting diameter; the shank is a standard 1/4 in hex that fits any 1/4 in quick-change chuck or three-jaw drill chuck.
What step do users often miss when installing the 56878 in a powder-actuated tool?
They forget to seat the countersink fully in the tool nose so the 100-degree pilot aligns with the fastener guide; a loose fit causes wobble and off-centre holes.
