The Freud 4 mm Through Hole Bit is an industrial-grade carbide tipped boring bit engineered for precise, repeatable through-hole drilling in both automatic and manual multi-spindle boring machines. Built to the high standards Freud is known for, this bit features a 60 deg. point angle for accurate hole location, a 10 mm shank with an adjustable top screw for broad machine compatibility, and a right-hand rotation design suited to standard boring machine setups. Whether you are working with hardwoods, softwoods, veneered plywood, solid surface materials, or composites, this through hole boring bit delivers the clean, accurate results required in professional woodworking and cabinet manufacturing environments.

Key Features

• Industrial carbide tips - provide long-lasting cutting edge retention, reducing tool replacement frequency and downtime in high-volume production settings.
• 60 deg. point angle - ensures accurate hole location when drilling through holes, resulting in cleaner entry points and tighter positional tolerances.
• 10 mm shank with adjustable top screw - makes this bit compatible with most boring machines, giving shops flexibility across different machine brands and setups.
• Right-hand (RH) rotation - matches the standard spindle direction of most drill presses and multi-spindle boring machines, so the bit installs and performs without modification.
• 70 mm overall length with 35 mm maximum hole depth - provides adequate reach for through-hole applications in standard panel and board thicknesses.
• Freud Limited Lifetime Guarantee - backs every bit with manufacturer support, giving buyers confidence in the long-term value of their investment.
• 4 mm cutting diameter - suited for small-diameter through holes commonly required in cabinet hardware, joinery, and panel assembly applications.

Why This Product

• Designed specifically for multi-spindle boring machines - automatic or manual - this bit integrates directly into professional cabinet shop workflows without requiring adapter hardware or machine modifications.
• The industrial carbide construction means the bit is built for superior performance and maximum service life, making it a cost-effective choice for production environments where bits are run continuously across a wide range of wood and composite materials.
• The 60 deg. point angle solves a common challenge in through-hole boring: accurate hole positioning. Clean, precise entry points reduce waste and rework, which is especially important when drilling veneered plywood or finished panel faces.
• With compatibility across composites, solid surface, veneered plywood, hardwoods, and softwoods, this single bit covers the full range of materials typically found in a cabinet or millwork shop, reducing the number of specialty bits needed on hand.

Frequently Asked Questions

What materials can the Freud TH40070R through hole bit drill?

This bit is designed to drill composites, solid surface materials, veneered plywood, hardwoods, and softwoods. It is suited for use on both automatic and manual multi-spindle boring machines as well as drill presses and hand held drills.

What is the maximum hole depth this bit can achieve?

The Freud TH40070R has a maximum hole depth of 35 mm. The overall bit length is 70 mm with a 4 mm cutting diameter and a 10 mm shank.

Is the adjustable top screw on the 10 mm shank compatible with most boring machines?

Yes. The 10 mm shank with an adjustable top screw is designed to make this boring bit compatible with most boring machines, including standard multi-spindle units used in professional woodworking and cabinet manufacturing.

What does the 60 deg. point angle do for through-hole boring?

The 60 deg. point angle is specifically designed for accurate hole location when boring through holes. This geometry helps ensure that the bit enters the workpiece at the correct position, reducing positioning errors and improving hole quality in materials like veneered plywood and hardwoods.
