Star-M Japanese 601 Precision Drill Bits - Singles

Star-M 601 precision drill bits are a Japanese-made solution to one of the more frustrating drilling tasks in the workshop: getting clean, tear-free holes in wood, leather and plastics.

The geometry is what sets them apart. Each bit works in a logical sequence:

• Hooked spurs score and clear waste from the perimeter first
• Semi-circular wings cut slightly deeper, parting the waste cleanly from the surrounding material
• A curved cutting edge then planes the waste out and evacuates it up the flutes

The result is consistently crisp holes with minimal breakout -- particularly valuable when working with materials that tend to grab, tear or melt under a standard twist bit.

A few things worth knowing:

• Use a low speed setting for plastics to avoid heat build-up and melting
• Use your highest speed setting for fibrous materials like leather and end grain
• Introduce the bit gradually rather than pushing straight in

Precise, well-engineered and built to a standard you'd expect from Japanese toolmaking.
