Plain Press Fit Drill Bushing

• Headless drill bushings are highly accurate cylindrical bushings
• Headless drill bushings are manufactured from the high carbon steel & hardened to 60-64 HRC
• OD are grounded with micron tolerance limits for press fit purpose, & Lead’s are provided for entry purpose
• ID are honed with micron tolerance limits
• Marking are done for easy Identification

Renewable Drill Bushings

Renewable Drill Bushings are used where rapid change over of hole size is required. The bushing can replaced at ‘end of life’ easily by unlocking the bushing and slipping it out the liner. When drilling different sized holes through a fixture, the renewable bushing range can be quickly removed using the slip or lock feature.

SERRATED Groove Drill Bushings

SERRATED Groove Drill Bushings are fully STRAIGHT knurled Bushings. It is designed to be cast-in to the fixture or mold. Popular in the resin and composite industries. Composite resin runs through the grooves to lock the bushing in place. The combination of the groove(s) and the diamond knurling form a strong resistance to axial and rotational movement. Serrated or diamond knurled bushings do not feature a ground OD, whilst this makes them more economical, the bushing must be accurately located using the bore. Alignment pins can be used where appropriate in a fixture.

Bullet Nose Pin

Bullet Nose Pins are also known as relieved pins. Bullet nose pins are used with a mating liner bush to create an accurate alignment and locating system. Using locating pins prevents binding of the work pieces. For simple installation, the OD of the pin body and the liner are the same, giving the option of one pass machining of both pates. The pins head and body are concentric to 0.0005 TIR

INCH and Metric STANDARDS / Heat treated to HRC 50-55 / Black oxide finish

Dowell Pins

• Dowel pins are precision hardened and ground parallel pins. Precision dowel pins are engineered to tight tolerance limits, for accurate locating and alignment in drilled and reamed holes
• Types of hardened dowel pins are either plain or tapped, also known as internally threaded or a threaded dowel pin. Metric (mm) or imperial standard measurements to DIN, ISO 8734 or BS 1804
• Custom dowel pins to drawing can also be quoted and manufactured to most customer requirements. B&T also manufacture a tapped dowel pin extractor tool in metric sizes M3 – M10 and also to BSW, BSF, UNC, and UNF upon request
