IRWIN Speedbor Max 3-Piece Wood Drill Bit Set (5/8-in, 3/4-in, 1-in)

Overview

Meet the IRWIN Speedbor Max 3-Piece Wood Drill Bit Set, engineered to help you create clean, confident holes in wood with less effort. The set combines three commonly used sizes with a design that supports smoother starts, faster chip ejection, and durable performance in a variety of woodworking tasks. It’s a practical choice for hobbyists and professionals who value consistent results without sacrificing control.

What makes these bits stand out

The core features work together to make drilling feel more predictable and efficient, especially when you’re working on frames, cabinetry, or quick-drafting projects. The tri-flute design helps moves chips away quickly, reducing friction and reducing heat buildup. Cutting spurs with three edges add durability for repeated use through soft and hardwoods alike. A full screw tip encourages self-feeding action, taking some of the bite out of starting holes and keeping your drill steady as you work.

• Tri-flute configuration promotes faster chip ejection for cleaner holes
• Cutting spurs with three cutting edges enhance durability during tough drilling
• Full screw tip enables self-feeding starts, reducing wobble
• Grooved hex shank helps prevent slipping in the drill chuck or bit extension
• Fits standard 1/4-inch quick-change chucks for quick setup and swap-outs

What you get and how to use it

This set includes three sizes to cover a range of wood drilling needs: 5/8-inch, 3/4-inch, and 1-inch. Use them for rough-through holes, medium precision tasks, or creating countersinks where you need a clean exit. The bits are designed to perform with standard 1/4-inch chucks, making them a versatile addition to most tool kits.

• 5/8-inch for mid-sized holes in boards and panels
• 3/4-inch for quicker, larger openings without excessive pressure
• 1-inch for deep or starting holes in softer woods or framing tasks

The durable construction helps you approach woodworking projects with confidence, while the self-feeding tip and hex shank reduce slipping and wandering in the chuck. While results will vary with material and technique, this trio is designed to help you achieve consistent, professional-looking holes with less fuss.
