Freud 3/8" (Dia.) Through Hole Bit is a precision-engineered industrial carbide tipped boring bit built for woodworking professionals who demand accurate, clean through holes in a wide range of materials. Designed specifically for multiple spindle boring machines - as well as drill press and hand held drill applications - this right-hand rotation bit features a 60 deg. point angle that ensures precise hole location every time. Whether you are drilling hardwoods, softwoods, veneered plywood, solid surface, or composite materials, the Freud TH93857R delivers consistent performance on both automatic and manual multi-spindle boring machines, making it a reliable choice for cabinet shops, millwork operations, and production woodworking environments.

Key Features

• Industrial carbide tips - provide superior hardness and edge retention, extending tool life significantly compared to standard high-speed steel bits when boring hardwoods and composites.
• 60 deg. point angle - enables accurate hole location for through holes, reducing wandering and improving placement precision on every pass.
• 10mm shank with adjustable top screw - ensures compatibility with most boring machines so you can drop this bit into your existing setup without additional adapters.
• Right-hand rotation (RH) - matches the standard spindle direction on the vast majority of multi-spindle boring machines and drill presses, making this bit a straightforward fit.
• 57.5mm overall length with 27mm maximum hole depth - sized appropriately for through-hole applications in cabinet and furniture panels without excessive bit overhang.
• Freud Limited Lifetime Guarantee - backs the bit against manufacturing defects, giving you confidence in your tooling investment over repeated production use.
• Designed for superior performance and maximum life - the combination of carbide tips and precision geometry means fewer bit changes and lower tooling cost per hole on the production floor.

Why This Product

• The 60 deg. point angle is specifically optimized for accurate through-hole location, solving the common problem of bit wander when starting holes in veneered plywood and composite panel materials.
• The 10mm shank with adjustable top screw makes this bit broadly compatible with most multi-spindle boring machines, so you do not need a dedicated or specialty machine to put it to work.
• Industrial carbide tipping means this bit handles the full range of production materials - from soft pine to dense hardwoods and solid surface - without needing to switch to a different bit for each stock type.
• Backed by the Freud Limited Lifetime Guarantee, this boring bit is a long-term tooling solution rather than a consumable, supporting cost control in high-volume woodworking and cabinet production environments.
