Boneham SF6422MH Slip-fixed Drill Bushing 0.625 in Id Steel

Product Description

The BONEHAM SF6422MH is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, this bushing features a 0.625 inch inside diameter, a 1 inch body outside diameter, and a 1.375 inch length under the head. The inside diameter is held to a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate tool guidance and repeatable hole location. Constructed from steel, it provides the durability required for repeated production drilling cycles. The headed design allows it to seat firmly in a liner bushing without additional fasteners for most applications.

This bushing is intended for use in drill jigs, fixtures, and tooling plates in manufacturing, machining, and metalworking environments. It is installed by machinists and toolmakers where slip-renewable bushing systems are used. The SF configuration is a standard industry type suitable for applications requiring a renewable bushing that can be inserted and removed without special tools. The head outside diameter measures 1.4375 inches and the head height is 0.375 inches, fitting standard counterbore configurations matched to the SF series.
