Gun Drill Insert Bushings: GDI Type

BONEHAM’s ‘GDI Type’ bushings are high precision bushings for gun-drilling machines. These gun drill insert bushings are for use in the ’GDL Type’ master bushing manufactured by Boneham. Together, these bushings form a highly accurate and concentric system. The advantage of using this two-piece bushing system, is increased flexibility over the GDE-Type, one-piece solution. Each ‘GDL Type’ bushing can hold a range of GDI inserts, making interchangeability straight forward. Bushings can be changed quickly due to drill size changes or after wear.

Boneham’s GDI Type gun drill bushings come in 6 OD sizes as standard. Ranging from 13/64 to 1″. With customer specified bore range from .0635″ to .7656″. Boneham can manufacture gun drill bushings to customer requirement, offering 3/4″ and 1″ length gun drill insert bushings upon request. Gun drill bushings should be replaced once worn. Concentricity is paramount. For information on the corresponding GDL Inserts, please download the catalogue page.
