Description

The Ultimate in flush trim bits – if you use a lot of templates or use a router bit to flush trim, then this is the best that you can buy. These Ultimate Flush Trim Bits are perfect when working with templates or when using a router to flush trim matching wood surfaces. Whiteside’s compression spiral design, with a 7/8" diameter bearing guide, makes this bit easy to use in the router and produces a superior quality trimmed edge. The Ultimate Flush Trim series brings industrial engineered bits, previously manufactured for CNC machines, right into your shop.

The Pattern Bit has a bearing on the shank end of the bit allowing for a template to be placed on top side of the piece to be duplicated. Featuring a plunge tip for versatility, the 7/8" carbide compression bit design creates a high shear angle for perfect cuts every time.

The Flush Trim Bit has a bearing on the end of the bit allowing for a template to be placed on bottom side of the piece to be duplicated. The 7/8" carbide compression design creates a high shear angle for perfect cuts every time.

The Combination Bit has a bearing on the end of the bit and on the shank allowing for a template to be placed on either side. The 7/8" carbide compression design creates a high shear angle for perfect cuts every time.

WOOD magazine review

Oversize spiral bits eliminate flush-trimming tear-out

Review Summary

In my shop, flush-trim router bits see lots of action. They get called on to rout rough-cut curved workpieces to identically match a template, trim inlays or solid-wood plywood edging flush, and make proud box joints and dovetails flush. But the small diameter of most trim bits can tear out wood fibers occasionally. The 7/8" diameter of Whiteside’s solid-carbide Ultimate Trim Bits creates a shallower shear angle than 1/2" bits, netting a cleaner cut.
It also allows Whiteside to install a bearing above the cutters on its pattern bit without reducing the 1/2" shank—the first bit to do this—maintaining maximum strength and preventing chatter. These compression-spiral bits use upward and downward cutting angles to simultaneously rout edges from the top and bottom faces toward the middle, eliminating tear-out. I trimmed numerous edges with these bits, from proud dovetails and box joints to plywood edging to curvy shelf brackets, and never once suffered grain tear-out. Whiteside offers these bits in three configurations, but if you can buy just one, get the combination bit with both top and bottom bearings. —Tested by Bob Hunter, Tools Editor
