Burdon detachables utilize a coupling which locks the tip in a strong,
straight and concentric unit on the shank. One shank can be used for a
multitude of tips and tip diameters. The Burdon detachable gundrill
coupling allows drill tips to be easily attached and detached. Two
precision bearing diameters are well spaced to give straightness and
concentricity. Special thread clamps join couplings to allow minimal oil
leakage and deliver maximum torque for gundrilling.
Economical Burdon detachables save money by utilizing one shank for many
drill heads of various diameters. Adaptation of existing drill shanks
may be possible. Labor is reduced by ease of handling in the machine and
on the shop floor. Extension shanks are available to increase drill
length. Drill tips can be easily sharpened when detached from their
shanks .
When returning drills for re-tipping you need
only return the used carbide head section, saving packaging and freight costs.
