Master Deep Mortising and Heavy Stock Removal with the Freud Extra-Long 5/8 Inch Router Bit

Overcome the limitations of standard router bits with the Freud 12-142 5/8 Inch Double Flute Straight Bit. Designed for serious woodworking challenges, this "extended reach" cutter boasts a substantial 2-inch carbide cutting height and an impressive 4-inch overall length. This specific geometry makes it the ultimate tool for deep mortising, cutting through thick hardwood slabs, or executing deep dados in a single tool setup. Anchored by a heavy-duty 1/2-inch shank, the bit provides the critical stability required to dampen vibration and prevent chatter, ensuring clean, straight walls even when extended to its maximum depth.

Durability meets precision in the 12-142. It is crafted from Freud's exclusive TiCo Hi-Density Carbide, a proprietary micro-grain formulation engineered to withstand the intense heat generated during deep, heavy cuts. This ensures the cutting edge stays sharp up to four times longer than standard carbide bits. The tool features computer-balanced double flutes with optimized shear angles that slice cleanly through wood fibers, producing a splinter-free finish that minimizes sanding. With end-relieved tips facilitating smooth plunge cuts, this bit is a versatile workhorse for CNC machines, router tables, and handheld routing applications.

Key Features

  • Extra-Long Reach: 4-inch overall length allows for deep routing and accessing hard-to-reach areas.
  • Deep Cutting Capacity: 2-inch carbide height enables deep mortises and thick stock edge trimming.
  • TiCo Hi-Density Carbide: Specialized carbide blend resists heat and wear for extended tool life.
  • Heavy-Duty Shank: 1/2-inch shank provides maximum rigidity and safety for long-reach applications.
  • Perma-SHIELD Coating: Non-stick red coating reduces friction, prevents gumming, and resists corrosion.
  • Plunge Ready: Relieved tip geometry allows for efficient vertical drilling and pocketing.
  • Versatile Application: Ideal for CNC, table-mounted, and handheld routers cutting wood and composites.

Pro-Tip: While this bit features a massive 2-inch cutting height, attempting to cut that full depth in a single pass is dangerous and can damage your workpiece or the bit. To ensure a smooth finish and maintain safety, make multiple lighter passes of approximately 1/4" to 3/8" deep until you reach the full 2-inch depth.
