Countersink Categories > Import > Bell Type

PRODUCT DETAILS: When metal parts are machined on centers, as in turning or cylindrical grinding, it is always necessary to drill and countersink the center hole to serve as seats or bearings for the machine centers.  The Plain Type is by the most commonly used.  If the parts, to be machined, are to pass through a number of subsequent handlings, where there is a danger of marring the edges of the center holes, it is advisable to use the Bell Type.  They have an additional small 120 degree chamfer to protect the edges of the 60 degree hole.

Packaging: All sizes are individually packaged.
