57192 180-DEG bullnose identifies this Amana Tool corner rounding router bit as a dedicated 180 degree bullnose cutter for solid surface work, giving installers a precise match between part number and finished profile on repeat jobs. The 2-1/8 inch diameter cutting head shapes a wide bullnose across solid surface edges, so long countertop or panel runs keep a consistent profile from piece to piece. A 3/4 inch radius defines the curve of the bullnose, which sets the feel and look of the finished edge on worktops or similar parts. The 1 inch cutting height keeps the working portion of the bit within a controlled band, which helps when matching the edge detail to standard solid surface thicknesses. The 1/2 inch shank seats solidly in routers designed for this size, supporting stable cuts on heavier passes across solid surface materials.
The 3/4 inch radius on this router bit sets the exact size of the bullnose, so fabricators can plan edge reveals and profile transitions around a known curve. A 1-1/2 inch cut depth figure defines how far the bullnose profile engages into the edge, which helps when balancing top and bottom coverage on solid surface slabs. The 5/8 inch D1 dimension relates to a secondary diameter on the bit, supporting predictable clearance as the profile wraps the edge. With the 1/2 inch shank matching common professional router collets, installers can use standard machines while keeping the 2-1/8 inch diameter cutter stable under load. Together these dimensions give tradespeople a clear understanding of how the bit will perform before it ever touches the workpiece.
This carbide tipped corner rounding router bit is used on solid surface materials, aligning with the dedicated solid surface category callout. The 180 degree bullnose profile lets fabricators create a full round edge on countertops, panels, or similar solid surface components where a complete curve is desired. The ultra-glide ball bearing guide tracks directly along the edge, so the bit follows existing straight or curved layouts while maintaining the 3/4 inch radius. With a 2-1/8 inch diameter cutting head, the bit covers a broad edge area in one pass, which supports production-style routing on longer runs. The 1 inch cutting height further focuses the working area, so the bullnose can be kept within the typical thickness of many solid surface jobs without over-extending the profile.
The unique pilot bearing on this router bit allows production of a true 180 degree bullnose, which matters when the goal is a fully symmetrical round edge from top to bottom. Because the bearing guides the bit, the 3/4 inch radius stays constant, reducing profile drift and helping pieces align visually when installed side by side. The 2-flute, carbide tipped design balances cutting forces around the 2-1/8 inch diameter, which supports smoother rotation and can yield a more uniform surface ready for subsequent finishing steps. The 1/2 inch shank supports a secure hold in compatible routers, which is especially important when rotating a relatively large diameter cutter at operating speed. The overall length of 3 inches positions the 1 inch cutting height in a practical working zone, helping installers repeat the same bullnose setup across multiple solid surface runs.
The 57192 180-DEG bullnose bit, with its 3/4 inch radius and 2-1/8 inch diameter, produces a true 180 degree bullnose, giving a fully rounded edge on solid surface workpieces.
The ultra-glide ball bearing guide pilots along the workpiece edge, keeping the 3/4 inch radius aligned so the bullnose profile stays consistent from one end of the solid surface to the other.
This corner rounding router bit is specified for solid surface material, so fabricators can match its bullnose profile to common solid surface countertop and panel applications.
The 1/2 inch shank fits routers designed for this collet size, giving a solid grip to support the 2-1/8 inch diameter cutter while forming the 180 degree bullnose on solid surface edges.
The 1 inch cutting height keeps the active cutting area focused, which helps align the 180 degree bullnose within typical solid surface edge thicknesses during fabrication.
The 57192 part number identifies this specific carbide tipped, 2-flute, 3/4 inch radius, 2-1/8 inch diameter bullnose router bit for solid surface work from Amana Tool.
The 57192 180-DEG bullnose router bit from Amana Tool combines a 3/4 inch radius, 2-1/8 inch diameter, and ultra-glide ball bearing guide to form a true 180 degree bullnose on solid surface. With a 1/2 inch shank, 1 inch cutting height, and 1-1/2 inch cut depth, the bit offers clear, predictable geometry for edge work. For tradespeople shaping solid surface countertops or panels, this carbide tipped, 2-flute router bit provides a defined profile tied directly to part number 57192 for repeatable results.
