A Stainless-Optimized Router Bit Built for Sink Fabrication
The Amana Tool Lansen 7/8" x 2-1/4" Stainless Steel Sink Edge Bit is a purpose-built routing solution for fabricators who work with stainless steel sinks. With a 15-degree chamfer geometry and a 1/4" shank, it cuts the beveled edge profile needed when fitting a sink opening — putting the right angle on the countertop material so the sink seats cleanly and accurately.
Key Features
• Stainless Steel Sink Application: Ground specifically for the edge-profile work required when installing stainless steel sinks, not a general-purpose chamfer bit.
• 15-Degree Chamfer Geometry: The 15-degree bevel angle matches the edge profile called for in stainless sink fabrication workflows.
• 2-Flute Cutting Design: Two flutes deliver a cleaner, more balanced cut and help reduce heat buildup during the pass.
• 1/4" Shank: Fits the 1/4" collet routers common in countertop shops and on portable handheld units used at the bench or in the field.
• Lansen Series Build Quality: Amana Tool's Lansen line is engineered for professional fabrication use, with consistent edge geometry from the first pass.
Where This Bit Earns Its Place
Stainless sink installation requires a precise edge profile at the countertop cutout so the sink rim seats flush and the final joint looks intentional. A generic chamfer bit gets you a bevel, but it is not ground to the angle that stainless sink fabrication calls for. This bit is. It handles the bevel cut in solid surface, laminate, and similar countertop materials where the fabricator needs to profile the cutout edge before the sink drops in or bonds to the underside. It is the right tool to reach for when the substrate is prepped and the angle needs to be exact.
Material, Construction, and Performance
Amana Tool builds the Lansen line for countertop and cabinet shop environments where bits run hard and consistency matters across a full production day. The 2-1/4" overall length gives enough reach for standard countertop thicknesses without requiring an extended shank. The 7/8" cutting diameter covers the profile pass in a single controlled sweep. Two flutes keep chip evacuation moving and cut heat down compared to a single-flute profile. The 1/4" shank keeps the bit compatible with lightweight routers — an advantage when the fabricator is working a portable unit around the cutout rather than running a fixed table.
The Right Shop for This Bit
This bit belongs in countertop fabrication shops that install stainless steel undermount or drop-in sinks regularly and need a dedicated edge-profile bit rather than a repurposed chamfer. It is also a practical addition for finish carpenters and kitchen installers who cut their own sink openings on-site and want the correct bevel angle dialed in before the sink goes in. If your work involves stainless sink openings at volume, keeping a dedicated Lansen edge bit on hand means one less variable on installation day.
What countertop materials can I use this bit on?
The bit profiles the countertop cutout edge — solid surface, laminate, and similar sheet materials are the typical substrates in stainless sink fabrication workflows. It is not designed to cut into the stainless sink itself.
Does the 15-degree angle match Karran Edge sink installation requirements?
Karran's documented bevel bit for Edge stainless sink seamless installation is a 24-degree bit for solid surface and a 10-degree bit for laminate. This Lansen bit is a 15-degree chamfer, which sits between those two angles and is designed for stainless sink edge profiling as specified in its product documentation. Confirm the required angle against your sink manufacturer's installation guide before routing.
Will this bit work in a standard handheld router?
Yes. The 1/4" shank fits any router with a 1/4" collet, including the portable handheld units commonly used for sink cutout work at a countertop or on a bench.
Is this bit sold individually or in a set?
This listing is for a single bit. Order the quantity you need for your shop stock.
The Right Angle, Ready When the Sink Is
Sink fabrication does not leave room for the wrong bevel on the day of install. Having a dedicated stainless sink edge bit with the correct 15-degree geometry means the profile cut is done right the first time, and the job keeps moving.
