Boneham H206EU Press Fit Headed Drill Bushing Type H

Product Description

The BONEHAM H206EU is a Type H press fit headed drill bushing machined from steel for use in jig and fixture applications requiring precise hole location and repeatable drilling accuracy. With an inside diameter of 5/32 inches and a body outside diameter of 5/16 inches, this bushing guides drill bits, reamers, and other cutting tools to consistent positions across production runs. The hardness rating of 60 to 65 HRC ensures long service life under high-cycle conditions. A head outside diameter of 27/64 inches and a head height of 1/8 inch provide a positive stop against the jig plate surface. Machinists, toolmakers, and fixture builders install this type in tooling plates where the bushing is pressed in permanently and not intended for removal or exchange.

This bushing is suited for use in drill jigs, fixture plates, and production tooling in machine shops, fabrication facilities, and manufacturing environments. Its press fit installation method makes it appropriate for fixed-bushing applications where the drill station does not require bushing changes between operations. The 3/8 inch length under head accommodates standard jig plate thicknesses common in general metalworking setups. It conforms to ANSI standards, making it compatible with standard tooling layouts used across a wide range of industrial drilling operations.

Key Features

• Type H headed press fit design provides a positive stop against the jig plate surface
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures precise drill guidance
• 60 to 65 HRC hardness resists wear under repeated drilling cycles
• Steel construction for durability in production tooling environments
• Meets ANSI standards for drill bushing geometry and dimensional accuracy
• Non-renewable design — permanently installed for fixed drill station applications

Compatibility

Designed as an ANSI-standard press fit headed drill bushing for permanent installation in drill jigs and fixture plates used in general metalworking and production machining applications.

Installation Notes

Press fit bushings are installed by toolmakers or machinist-trained personnel using an arbor press or similar controlled pressing equipment to seat the bushing flush with the jig plate. Power down all associated machinery before installing or inspecting tooling plates. Do not hammer the bushing directly without a proper driver — uneven force can distort the bore or damage the head seating surface. Once pressed in, this bushing is not designed for removal or reuse.
