What’s inside

• Five standard sizes: #4 and #6 twist bits; #8, #10, #12 tapered twist bits
• Each size is paired with a companion drill bit for precise depth and clean entry

Why upgrade to the 4-flute design

• Enhanced sharpness and cutting stability for smoother drilling
• Multi-flute layout distributes the cutting load, helping extend the bit’s life

Sharp drilling, durable performance

• Made from premium M2 cobalt HSS for superior wear resistance and consistent results
• Forged for high efficiency and long service life in wood-based materials

Easy to use and maintain

• Universal 1/4" hex shank supports quick tool-free changes
• Shavings clear repeatedly to reduce clogging and maintain smooth operation

Pre-lubrication and care

• Factory pre-lubrication helps prevent rust and reduce friction; a light oil residue is normal
• Store in the included box to keep bits organized and protected

Ideal applications

Perfect for creating clean, uniform countersinks in wood, plywood, MDF, and other wood-based materials, whether you’re finishing hinges, hardware slots, or decorative inlays. While designed for wood, the set’s robust material allows reliable performance across common workshop tasks.

Note: Drill bits #4 and #6 are standard twist bits; #8, #10, and #12 are tapered twist bits.
