Carbide compression router bit

The SPEED TIGER ISEUD1-4-2 is a solid-carbide spiral bit with up-down compression geometry. It has a 1/4-inch shank, a 1-inch cutting length and a 2-1/2-inch overall length. Two flutes are ground in an ISO-9001 facility for consistent edge quality. The bit is designed for clean cuts in wood, plywood, MDF, hardwoods and softwoods.

Who should use this bit

CNC operators and woodworkers who need tear-out-free edges on double-sided veneers or laminates will benefit from the compression design. The micro-grain carbide withstands abrasive composites such as MFC and particle board. Buyers who need a larger shank diameter or a longer cutting length for deep mortises cannot use this bit.

Critical specification

The up-down compression geometry is the single feature that determines suitability. It shears fibres upward on the bottom and downward on the top, preventing splintering on both faces of the workpiece. Without this geometry a standard up-cut or down-cut bit will leave a ragged surface on one side.

Questions about this item

How does the up-down compression cut affect edge quality on plywood and MDF?

The opposing flutes shear fibres toward the centre, giving clean top and bottom edges on double-sided boards without tear-out.

What shank diameter does the bit use and which collets accept it?

The shank is 1/4 inch, so it fits any standard 1/4 inch ER or collet chuck used on CNC routers and handheld machines.

What overall length and cutting depth should I plan for in my tool holder?

Overall length is 2-1/2 inches with a 1 inch cutting length, leaving 1-1/2 inches for collet engagement and clearance.
