Meet the Freud TH12770R 15 mm through-hole bit — a precision tool built for serious woodworking projects. Designed for use with multiple spindle machines, this boring bit delivers clean, repeatable through-holes with a 60° point that helps locate the hole exactly where you intend. The result is accurate hole placement that reduces misdrilling and rework.

Compatibility and construction:

• Diameter: 15 mm
• Shank: 10 mm, enabling compatibility with a wide range of boring machines
• Top screw: adjustable top screw ensures secure mounting and reliable performance on most boring systems
• Point geometry: 60° point for precise hole location in through-holes
• Brand lineage: Freud/Diablo TH12770R, built with the brand’s reputation for accuracy

Practical applications:

• Cabinetry and furniture hinge installations where accurate through-holes are critical
• Joinery and dowel work requiring clean, true holes through solid wood, plywood, or composites
• Electrical pass-throughs or hardware runs where alignment matters

Why choose the Freud TH12770R over other boring bits?

• Engineered to work with multiple spindle machines, reducing the need for adapters and special tooling
• 60° tip geometry minimizes wandering and improves first-pass accuracy, saving time
• Reliable performance with a compact design that helps maintain steadiness during boring

Tips for best results:

• Clamp your workpiece securely and use a backer board to prevent tear-out on the exit side
• Start with a shallow pilot hole if drilling into dense woods or hardwoods
• Keep feeds steady and avoid excessive binding; lubricate with a little wax or oil if working with particularly hard material
• Clear chips frequently to maintain smooth cutting and prevent overheating
