Our production quality spiral bits combine effective chip removal with a continuous shearing action cut not obtained from a standard straight bit. You'll get smoother cutting action with better results. All bits two flute, solid carbide. USA

Up-cut Bits provide faster cutting while they pull chips up and out of the work or towards the router. They are excellent bits to use when cutting material in a table mounted router. They hold the work piece to the router. Ideal for mortise and tenon, grooving, slotting or routing deep blind holes.

Down-cut Bits cut slower and push chips away from the router to eliminate top surface splintering. Use for pattern cutting or when going completely through the board as it allows clear vision of the cutting line. Ideal for fine finish work such as veneers, laminates, inlays and repairs because they prevent upper edge tear outs. Use Down-cuts for trimming and sizing.

Router Saftey Tips:

• Always wear eye and ear protection.
• Always use properly sharpened bits.
• Never use bits that are dull or damaged.
• Shank must be completely inserted into collet and then backed-off approximately 1/16".
• Don't "bottom-out" bit in collet.
• Never partially insert bit into collet. Tighten securely and recheck periodically for possible slippage or "run-out" due to wear.
• Keep collet clean and replace if worn.
• Never start the router with the bit in contact with wood.
• Always feed your work in the proper direction against the bit rotation.
• Don't force feed the bit or overload your router, Feed at a constant moving speed to avoid burning the wood.
• Do not face tool's discharge when operating.
• Always unplug router when changing bits or making adjustments.
• Use a router table and fence whenever possible.
• Make sure your work piece is properly secured and use push blocks, sticks and featherboards whenever possible.
• Keep all your bits, bearings and assemblies clean, lubricated, and securely fastened. To avoid damage, store them properly in a pouch, box or tray.
• The bigger the bit, the lower RPM recommended (see chart).
