Product Description
The Diablo 1 5/8" Forstner Bit for Wood is a precision-engineered wood boring bit built for professionals and serious woodworkers who demand clean, accurate results. Designed to drill flat-bottom holes, pocket holes, and overlapping holes in hardwoods, softwoods, veneered plywood, and MDF, this high-speed steel bit delivers the control and cutting performance needed for fine woodworking and cabinetry applications. Featuring a double-ground serrated edge that minimizes splintering and chipping, the Diablo FB-012 is a reliable choice whether you are working with a drill press or a handheld drill.
Key Features
- High-speed steel construction with a double-ground serrated edge - reduces splintering and chipping for cleaner hole edges in hardwoods, softwoods, veneered plywood, and MDF
- Forged hardened steel body - delivers long bit life and maintains a sharp cutting edge through repeated use, reducing the need for frequent replacement
- Ultra-sharp center spur - guarantees accurate hole placement without walking on the material surface, giving you precise, repeatable results every time
- Drills straight, angled, and overlapping holes - gives you the versatility to handle a wide range of woodworking joinery and boring tasks with a single bit
- 3/8" shank with a minimum 3/8" chuck requirement - compatible with standard drill presses and handheld drills, making it easy to integrate into your existing tool setup
- 1 5/8" diameter cutting face - creates a wide, flat-bottomed bore well suited for dowels, hinges, shelf pins, and decorative inlays
Why This Product
- The double-ground serrated edge and ultra-sharp spur work together to produce smooth, splinter-free holes in delicate materials like veneered plywood and MDF - surfaces where bit quality makes a visible difference in finished work.
- Forged hardened steel construction means the bit holds its edge longer than standard bits, reducing downtime from resharpening or replacement when working through dense hardwoods.
- The ability to drill straight, angled, and overlapping holes makes this a versatile tool for complex joinery, pocket hole applications, and custom boring patterns - all with one bit.
- At 1 5/8" diameter and 3 1/2" overall length, this bit fills a specific size need for shelf pin routing, concealed hinge boring, and large-diameter dowel work where accuracy and clean entry matter most.

What makes the Forstner bit's spur design important for accurate drilling?
