Irwin Marples wood drilling Forstner bits are constructed of tough carbon steel to stay sharp and produce precise flat-bottomed (blind) holes and pocket holes. The ultra-sharp cutting teeth use optimized angles to cut through hard and soft woods in significantly less time than traditional Forstner bits.

• 5/8" cutting diameter
• Tough carbon steel construction stays sharp
• Ultra-sharp knife edge design cuts hard and soft woods smoothly and efficiently
• Optimized cutting angles drill in significantly less time than traditional Forstner bits
• Drills clean flat-bottomed (blind) holes and pocket holes
• Reduced shank fits 3/8" and larger drills and drill presses

Tip: Clamp the workpiece and back it with scrap. A Forstner bit removes a wide, flat-bottomed disc of material and cuts cleanest when the stock cannot shift or tear out at the far side.
