The Freud 4 mm Diameter Through Hole Bit is an industrial-grade carbide tipped boring bit engineered for precise, clean through holes in a wide range of wood and composite materials. Designed for use on multiple spindle boring machines as well as drill presses and hand held drills, this bit delivers the reliable performance woodworking professionals and cabinetmakers demand. With a 10 mm shank fitted with an adjustable top screw, it integrates with most boring machines right out of the box, reducing setup time and expanding compatibility across shop environments.

Key Features

• Industrial carbide tips - provide long-lasting cutting edge retention, meaning fewer bit changes and lower tooling costs over time
• 60 deg. point angle - enables accurate hole location for through holes, reducing wandering and improving drilling precision on composites, plywoods, hardwoods, and softwoods
• 10 mm shank with adjustable top screw - ensures broad compatibility with most multiple spindle boring machines, minimizing the need for adapters or special tooling
• Right hand (RH) rotation - matches standard boring machine and drill press spindle direction, allowing straightforward installation without additional setup
• 57.5 mm overall length with a 27 mm maximum hole depth - sized for versatile through hole boring tasks across a range of workpiece thicknesses
• Freud Limited Lifetime Guarantee - backs the bit against defects, giving buyers confidence in the long-term value of this investment

Why This Product

• The 10 mm shank with adjustable top screw makes this bit compatible with most automatic and manual multi-spindle boring machines, so shops can add it to their existing setup without purchasing new toolholders or adapters.
• The 60 deg. point geometry is specifically suited for through hole applications, delivering accurate hole placement and cleaner entry points compared to general-purpose bits not optimized for this task.
• Industrial carbide tipping means the cutting edge holds up through repetitive production runs on hardwoods, softwoods, veneered plywood, solid surface, and composites - materials commonly encountered in cabinet and furniture manufacturing.
• Backed by Freud's Limited Lifetime Guarantee, this bit represents a professional-grade solution designed for superior performance and maximum service life in demanding multi-spindle boring operations.
