- Guide to Straight Bits
Whiteside produces several varieties of Flush Trim bit, with differences in edge geometry, bearing, and shank size that allow you to match the router bit to your router and workpiece. Despite the range of options, all flush trim bits work the same way - a bearing at the tip of the bit guides the cutter around the workpiece to create a clean, flush edge. All Whiteside flush trim bits have replaceable bearings.
Straight flute bits are versatile, high value choice for trimming edges. Like all of Whitesides's straight flute bits, the cutting edges are ground convex for an extra durable edge.
V-Groove flush trim add a simple v-shaped reveal to an otherwise standard straight flute flush trim bit.
Spiral Trim bits are available with UP or DOWN cutting flutes. Up-cutting flutes eject chips up towards their shank, prevent tear out on the bottom of the workpiece, and help hold the router to the workpiece. Down-cutting flutes eject chips away from the shank, and prevent tear-out on the top surface of your workpiece.
Combo Trim bit's have bearings at the top and bottom of the cutter so the bit can be used as a flush trim bit run along the workpiece, or as pattern and template bit to make copies.
Unless otherwise noted, the bits on the page have two flutes.
Replacement bearings, and bearing sets are available separately.
Available in a range of diameters, lengths of cut, materials, and flute designs, straight router bits can do it all. If you need to trim an edge, cut a dado or rabbet, trace a template, waste a mortise, inlay or carve some basic lettering a straight bit can get the job done.
Straight fluted bits are a good all around choice, although they are generally not able to plunge cut. Bits of 1/4” and above are almost always carbide tipped for extra toughness, and will usually have two cutting edges. Smaller diameter bits are more typically solid carbide, and ground with a single cutting edge.
Spiral bits have cutting edges that wrap around the bit in a helix, for a smooth surface finish on the workpiece, and excellent chip clearing in enclosed feature. Most spiral bits are plunge cutting. Whiteside's solid carbide spiral bits are offered in up cut, down cut, and compression cut (up and down), for a range of chip clearing, and tear-out reducing options.
Undersized plywood bits are handy bits, for single pass cutting of dados, and slots correctly sized to common sheet goods, and plywood.
Router bits with a bearing, or pilot, are typically called: Trim, Flush Trim, Pattern, or Template Bits.
Flush Trim Router bits have a bearing or pilot at the end of the bit. The Bearing runs along the workpiece to allow the blades to “trim” veneer, laminate, or just about any material to a clean edge.
Ultimate Flush Trim Router bits are Whiteside's top of the line professional flush trim, and template bits.
Pattern and Template Bits have a bearing above the flutes of the bit, where the cutting edges meet the shank. The bearing runs along a template or pattern laid on-top of the workpiece, trimming the workpiece to match. Use Template bits to make copies of a shape, rout out material for inlay, or to clean out the bottom of a Dado made on a table or chop saw.
Replacement Bearings and Bearing Sets are available in a range of sizes.

Fine Wood Working had this to say about Whiteside in their May June 2007 Router-bit review: "At the end of the day, the Whiteside and the Eagle bits had risen to the top of the mix, tying for the highest score. Lee Valley had the second-highest score, followed by Southeast and Woodtek in a tie for third. By the way, Whiteside also had the best bit when we reviewed straight bits in our August 1999 issue (FWW #137). We named the Eagle and Whiteside bits best overall. And, since the Whiteside had one of the lowest prices of the top bits, we also named it best value."
