Flat Drill Bit 12 mm x 160 mm by 14 Degrees East (model DT4812)

Flat drill bit 12 mm x 160 mm by 14 Degrees East (model DT4812) is a spade-style wood bit engineered for fast, efficient drilling in timber and similar soft materials. The bit has a 12 mm cutting diameter and 160 mm overall length, with a flat blade profile that clears chips quickly and a centering point that helps produce accurate starts. It is compatible with standard handheld and powered drills used in carpentry, joinery and general DIY work.

Advantages

The flat blade design enables rapid material removal and produces clean, relatively flat-bottomed holes in wood. The centering point reduces wandering on the workpiece, improving positional accuracy without the need for pilot holes in many cases. The 160 mm overall length gives sufficient reach for through-holes in thicker boards and assembly tasks, while the 12 mm diameter matches common dowel and fastener sizes. The shaft is sized for mounting in standard drill chucks, making the bit suitable for both manual and powered drilling setups.

Suitable for

• Drilling holes in softwoods, hardwoods and plywood
• Installing dowels and through-bolts where a 12 mm hole is required
• Carpentry and joinery work such as framing, cabinetmaking and shelving
• General DIY tasks including furniture assembly and repairs

Key specifications

• Cutting diameter: 12 mm
• Overall length: 160 mm
• Type: flat/spade (flat blade) bit with centering point
• Material compatibility: wood and similar soft materials
• Mounting: suitable for standard drill chucks

How to use

Secure the flat drill bit in the drill chuck and ensure it is tightened to prevent slipping. Mark the drilling position on the workpiece and, if required for extra precision, clamp the workpiece to prevent movement. Align the centering point with the mark and start drilling at low speed to establish the hole, then increase speed and apply steady pressure while allowing the bit to clear chips. For through-holes, back the bit out occasionally to remove debris and reduce heat buildup. After use, clean the blade of wood chips and store the bit in a dry place.

Usage recommendations

Use the flat drill bit at moderate speeds recommended for the type of wood being drilled; hard woods require slower speeds than softwoods. When drilling close to edges, support the underside of the workpiece to reduce splintering. Wear appropriate eye protection and secure the workpiece to maintain safe, controlled drilling.
