The Freud 5 mm Through Hole Bit (TH50070L) is an industrial-grade carbide tipped boring bit engineered for precision drilling on both automatic and manual multi-spindle boring machines. With a 60 deg. point angle that guides the bit to an accurate hole location, this through hole bit is built to deliver consistent, repeatable results across a wide range of materials - from hardwoods and softwoods to veneered plywood, composites, and solid surface materials. Backed by Freud's Limited Lifetime Guarantee, it is designed for superior performance and maximum tool life in demanding production environments.

Key Features

• Industrial carbide tips - extend cutting life and maintain sharp edges through repeated use on hard and abrasive materials, reducing downtime and replacement costs.
• 60 deg. point angle - ensures accurate hole location for through holes, so boring operations stay precise even across multiple spindle passes.
• 10 mm shank with adjustable top screw - provides broad compatibility with most boring machines, making this bit easy to fit and secure without adapters.
• Left Hand (LH) rotation - engineered specifically for left-hand spindle configurations on multi-spindle boring machines, ensuring proper cutting action and clean hole entry.
• 70 mm overall length with 35 mm maximum hole depth - gives enough reach for through hole boring while keeping the bit rigid and stable during operation.
• Compatible with drill press and hand held drill tools - offers flexibility for both machine-mounted production work and manual drilling applications.
• Freud's Limited Lifetime Guarantee - provides long-term assurance of quality, so buyers can rely on this bit for sustained professional use.

Why This Product

• Designed specifically for multi-spindle boring machines with a 10 mm shank and adjustable top screw, this bit installs securely and runs true without the need for special adapters or machine modifications.
• The 60 deg. point angle is purpose-built for through hole applications, delivering accurate hole placement that reduces tear-out and rework when boring hardwoods, softwoods, composites, veneered plywood, and solid surface materials.
• Industrial carbide construction means this bit holds its cutting edge significantly longer than standard steel bits, making it a practical choice for high-volume production boring operations.
• Left Hand rotation matches the spindle direction of LH-configured boring machines, ensuring the bit cuts as intended and produces clean, well-defined holes rather than burnished or oversized openings.

Frequently Asked Questions

What types of machines is this through hole bit designed for?

This bit is designed for multiple spindle boring machines - both automatic and manual configurations. It is also compatible with a drill press and hand held drill for more versatile use. The 10 mm shank with an adjustable top screw makes it compatible with most boring machines without additional adapters.

Why does this bit use left hand (LH) rotation, and how do I know if it is right for my machine?

The LH designation means this bit is engineered to rotate in a left-hand (counter-clockwise) direction. This matches the spindle configuration of LH-designated boring machine heads. Before purchasing, confirm that your boring machine spindle or head is set up for left hand rotation, as using an LH bit on an RH spindle will not cut properly.

What materials can the Freud TH50070L bore through?

This through hole bit is designed to drill composition materials, solid surface materials, veneered plywood, hardwoods, and softwoods. The industrial carbide tips give it the durability needed to handle both dense hardwoods and engineered composite panels in production environments.

What is the maximum hole depth this bit can achieve?

The Freud TH50070L has a maximum hole depth of 35 mm. The overall bit length is 70 mm, with a 5 mm diameter cutting section and a 10 mm shank. It is specifically designed for through hole boring, so it is best used in applications where the bit passes completely through the workpiece within the 35 mm depth limit.
