Import 20995 Bridge Construction Reamer 3/4 in Hss Spiral

Product Description

The IMPORT 20995 is a bridge-construction reamer designed to enlarge and finish drilled holes in structural steel and heavy fabrication applications. Built from high speed steel (HSS), this tool delivers the edge retention and toughness required for reaming through hard ferrous materials on job sites and in fabrication shops. It features a 3/4 inch cutting diameter, a 1/2 inch Morse taper shank, a 5-1/2 inch overall length, and a 5-flute spiral configuration that promotes smooth chip evacuation and a consistent finish bore. Licensed tradespeople and structural ironworkers rely on this style of reamer to align bolt holes in bridge and building framework connections.

This reamer is suited for structural steel assembly work where bolt holes require reaming to final diameter for close-tolerance pin or fastener fit. Typical applications include beam-to-column connections, gusset plate fabrication, and field alignment of mating steel members. The spiral flute geometry makes it appropriate for use in both manual and machine-driven setups where controlled material removal is required. It is commonly used by ironworkers, millwrights, and heavy fabrication shops handling structural connections that demand precise hole sizing.

Key Features

• 3/4 inch cutting diameter for standard structural bolt-hole sizing
• High speed steel construction provides durability and edge retention on ferrous materials
• 5-flute spiral configuration promotes smooth chip evacuation and improved bore finish
• 1/2 inch Morse taper shank for positive drive in compatible drill presses and portable drills
• 5-1/2 inch overall length provides reach for typical structural member thicknesses

Compatibility

Designed as an OEM-style replacement or standard tooling option for bridge and structural construction reaming operations requiring a 3/4 inch diameter, 5-flute spiral reamer with a Morse taper shank.

Installation Notes

This reamer is installed and operated by licensed ironworkers, millwrights, or trained fabrication personnel. Secure the Morse taper shank firmly in a compatible drill press spindle or portable magnetic drill before use. Always ensure the workpiece is clamped or fixed before beginning the reaming operation to prevent workpiece movement or tool breakage. Follow applicable OSHA and shop safety standards when operating rotary cutting tools on structural steel.
