The Freud 3/8" (Dia.) Through Hole Bit is an industrial-grade carbide tipped boring bit engineered for precision drilling on multiple spindle boring machines. With a 10mm shank and an adjustable top screw, this bit integrates seamlessly with most automatic and manual multi-spindle boring machines, making it a reliable choice for woodworking shops that demand consistent, accurate results across a wide range of materials - from hardwoods and softwoods to composites, solid surface materials, and veneered plywood. The 60 deg. point geometry ensures accurate hole location every time, reducing rework and material waste on through-hole applications.

Key Features

• Industrial carbide tips - deliver long-lasting cutting performance and resistance to wear, reducing the frequency of bit replacement in high-volume production environments.
• 60 deg. point angle - provides precise hole location for through holes, minimizing drift and improving accuracy on both automatic and manual boring machines.
• 10mm shank with adjustable top screw - ensures broad compatibility with most boring machines, so operators can switch bits quickly without needing specialized tooling.
• Left hand (LH) rotation - designed specifically for left-hand spindle configurations, making it the correct match for machines that require counter-clockwise bit rotation.
• 27mm maximum hole depth - suited for through-hole applications in typical panel and cabinet stock thicknesses.
• Freud Limited Lifetime Guarantee - backs the bit against defects, giving buyers confidence in the long-term value of their investment.

Why This Product

• Woodworking professionals who run multi-spindle boring machines need bits that hold up under repeated use - the industrial carbide construction of this Freud boring bit is built for superior performance and maximum life in production settings.
• Accurate hole location is critical in cabinet and furniture manufacturing. The 60 deg. point geometry eliminates guesswork and reduces the risk of misaligned through holes in veneered plywood, hardwoods, and composites.
• The 10mm shank with adjustable top screw means this bit fits most boring machines without adapters or special setups, saving setup time and keeping production moving.
• For left-hand spindle machines, using the correct LH rotation bit is essential for clean cuts and safe operation - this bit is purpose-built for that configuration.

Frequently Asked Questions

What machines is this through hole bit compatible with?

This Freud boring bit is designed for multiple spindle boring machines - both automatic and manual - and features a 10mm shank with an adjustable top screw that makes it compatible with most boring machines. It is also noted as compatible with drill presses and hand held drills.

Why does rotation direction matter, and what rotation does this bit use?

This bit uses left hand (LH) rotation, meaning it spins counter-clockwise. Using a bit with the correct rotation for your machine spindle is essential for clean, safe cutting. Using the wrong rotation can result in poor cut quality or unsafe conditions. Always verify your spindle direction before selecting a bit.

What materials can I drill with this 3/8" through hole bit?

This bit is suited for drilling composites, solid surface materials, veneered plywood, hardwoods, and softwoods - covering most standard materials used in cabinet, furniture, and panel manufacturing applications.

What does Freud's Limited Lifetime Guarantee cover?

Freud backs this boring bit with a Limited Lifetime Guarantee, which provides coverage against defects and supports the product's long-term reliability. Contact Freud directly for specific terms and conditions of the guarantee.
