This page lists our range of quality drill bits.
The range is specifically designed to cover the tapping
drill sizes and clearance hole sizes for the range of taps list. The use of the
correct drill size is crucial to successful tapping and tap life and some of the
sizes below are difficult to obtain on the high street.
The tap drill sizes quoted as standard ('Std') are the
tap manufacturers recommended size for full thread engagement. For many hobby
and non-critical applications, a larger size tap drill can be used to give less
thread engagement but reduced the risk of tap breakage - this may be preferable
when tapping the smaller size threads, particularly if you are new to thread
tapping. These drills are listed as Increased clearance ('Inc Clearance') and
will result in approximately 65% thread engagement
If the size you need isn't listed please e mail
us with your requirements.
