2-1/4 inch Forstner bit describes this Amana Tool FO-558 cutter sized for 2-1/4 inch holes, so office furniture builders can bore consistent telephone and computer wire grommet access openings across multiple panels. The 6 inch length lets the bit reach through thicker tops and workpieces, supporting grommet holes in deeper desks and multi-layer constructions. A 1/2 inch shank fits many heavy-duty drill presses and boring setups that accept that shank size, giving installers a solid interface when boring larger diameter holes. The specially designed geometry targets telephone and computer wire grommet access holes in office furniture, so the cutting profile supports a clean, round opening suited to common grommet styles used in desks and workstations.
This Amana Tool FO-558 bit uses a 1/2 inch shank, so it works in drilling and boring equipment that accepts a 1/2 inch round shank connection, giving installers a robust setup for 2-1/4 inch bores. The 6 inch overall length provides reach for applications such as thicker office furniture tops or stacked components where grommet wire access must pass through multiple layers. The Forstner design supports flat-bottom style holes, which is useful when creating clean grommet access where the bottom of the bore must sit accurately relative to the surface layout. The specially designed geometry for telephone and computer wire grommet access holes in office furniture aligns the tool to common desk and workstation layouts where organized cable routing is needed.
This 2-1/4 inch x 6 inch multi-tooth Forstner bit is specified for cutting telephone and computer wire grommet access holes in office furniture, so it is suited to desks, conference tables, and similar tops that need cable pass-throughs. The 2-1/4 inch diameter targets grommet-style openings typically sized in that range, giving casework and millwork shops a dedicated bit for that common hole size. The 6 inch length supports boring through thicker or doubled-up tops often used in higher-end office installations, allowing a full-depth cut without changing tools. With a 1/2 inch shank, the bit is sized for heavier drilling equipment, supporting stable boring of large holes used for wire management. The Forstner construction supports flat and clean-bottom bores where the opening must register accurately to furniture hardware layouts.
The multi-tooth cutting edges are designed for faster cutting and chip removal, which helps maintain control as the bit advances through the workpiece and supports productivity when several grommet openings are required in a run of parts. Precision ground and tempered tool steel provides sharp, durable cutting edges that help hold a consistent cutting profile, giving repeatable hole dimensions from the first panel to the last in a furniture project. The massive cutter body is designed to dissipate heat and resist burning, which reduces scorch marks at the edge of the bore on desk and cabinet surfaces. By resisting burning, the bit helps preserve the appearance of finished or pre-finished office furniture components around the grommet opening. Faster chip removal from the multi-tooth geometry also supports smoother drilling, as chips clear the cut more effectively while boring deeper holes.
