The Freud 9 mm Through Hole Boring Bit (TH90070L) is a precision-engineered, industrial carbide tipped boring bit built for multiple spindle machines - including both drill press setups and hand held drill applications. Designed to deliver accurate hole location in through-hole boring operations, this bit features a 60 deg. point geometry that guides the cutting edge into the workpiece with consistency across a wide range of materials, from hardwoods and softwoods to composites, solid surface, and veneered plywood. Backed by Freud's Limited Lifetime Guarantee, the TH90070L is a dependable choice for professional woodworkers and fabricators who demand performance and longevity from their tooling.

Key Features

• Industrial carbide tips - engineered for superior performance and maximum tool life, reducing replacement frequency in demanding production environments
• 60 deg. point angle - enables accurate hole location for through-hole boring, minimizing wander and ensuring consistent positioning across every operation
• 10 mm shank with adjustable top screw - ensures compatibility with most boring machines, making this bit versatile across multiple spindle setups without additional adapters
• Left hand (LH) rotation - specifically designed for machines that require left hand rotating bits, ensuring safe and correct operation
• 9 mm diameter with 70 mm overall length and 35 mm maximum hole depth - provides precise through-hole sizing in solid surface, plywood, hardwood, and softwood materials
• Freud's Limited Lifetime Guarantee - delivers long-term value assurance, giving buyers confidence in the tool's durability over its working life

Why This Product

• Purpose-built for multiple spindle boring machines - the 10 mm shank with adjustable top screw fits most automatic and manual multi-spindle boring machines, meaning less setup time and fewer compatibility concerns on the shop floor
• Industrial carbide construction means this bit holds up through high-volume drilling in composites, solid surface, veneered plywood, hardwoods, and softwoods - materials that quickly wear down lower-quality tooling
• The 60 deg. point is optimized specifically for through-hole applications, delivering accurate hole location that reduces waste and rework on finished panel goods and millwork
• Left hand rotation addresses the specific mechanical requirements of LH-configured boring machines, ensuring the bit is the correct match for those setups rather than a workaround

Frequently Asked Questions

What machines is the TH90070L compatible with?

This boring bit is designed for multiple spindle machines, including both drill press setups and hand held drills. The 10 mm shank features an adjustable top screw that makes it compatible with most automatic and manual multi-spindle boring machines.

Why does this bit use left hand (LH) rotation?

The TH90070L is specifically engineered for left hand rotation to match the mechanical requirements of LH-configured boring machine spindles. Using a bit with the correct rotation direction is essential for safe operation and proper chip evacuation during through-hole boring.

What materials can this boring bit drill through?

This carbide tipped through hole boring bit is rated for use in composites, solid surface materials, veneered plywood, hardwoods, and softwoods - covering the full range of materials commonly encountered in cabinet, furniture, and millwork production.

What does the 60 deg. point angle do?

The 60 deg. point geometry is specifically designed to provide accurate hole location for through-hole boring operations. It helps guide the bit into the workpiece precisely, reducing wandering and improving consistency across multiple holes in production runs.
