High Quality Bits
Leigh Brand carbide-tipped router bits are among the best you can buy. They are made with high quality C2 and C3 micro grain carbide for long bit life. Each bit is honed to a fine edge with 600 grit diamond wheels for smooth, efficient routing. All shanks are 1-3/4" long to handle the thickness of the finger assembly or accessory template. Leigh router bits are manufactured to ISO 9002 standards.
Shank Size
Every Leigh dovetail jig is shipped with 8mm shank router bits. They are considerably stronger and stiffer than 1/4" shanks, allowing smoother cuts and faster feed rates with a greater margin of safety. Routers with 8mm or 1/2" collets are required to use 8mm shank bits. A Leigh 1/2" to 8mm collet reducer, supplied with most Leigh dovetail jigs, allows 8mm shank bits to be used in 1/2" collet routers.
Through Dovetail Bit Selection
Leigh Super Jigs and the D1600 use 8º dovetail bits for through dovetail tails and one straight bit for pins. The dovetail bit's working depth (column B, Through Dovetail Bit Selection Chart below) must be equal to or slightly greater than the thickness of the pin board or drawer front. Always choose the smallest dovetail bit (column A) relative to the pin board thickness for that look of hand-cut elegance. Use the matching straight bit and template guidebush indicated in the chart.

Half-Blind Dovetail Bit Selection
In half-blind joints, pins and tails are routed with the same dovetail bit at the same depth of cut. The bit angle determines the nominal depth of cut, therefore, a bit of a given angle must cut at or very near a specific depth in order to make pins and tails fit together properly. Choose a half-blind bit with a cutting depth at least 1/8" less than the pin board thickness. Leigh offers five half-blind bits to suit board thicknesses from 1/2" to 7/8" or greater. For rabbeted or lipped drawers, choose a bit with a cutting depth slightly less than the rabbet's shoulder depth.
