Flat Wood Drill Bit 16 mm x 160 mm by 14 Degrees East (model DT4816)

Flat Wood Drill Bit 16 mm x 160 mm by 14 Degrees East (model DT4816) is a spade/flat drill designed to create clean through-holes in a variety of wood materials. With a 16 mm cutting diameter and a 160 mm overall length, this bit is intended for use in hand drills and drill drivers to deliver straight holes in softwoods, hardwoods, plywood and chipboard. The tip and cutting edges are shaped to reduce splintering and provide consistent bore quality for general woodworking and installation tasks.

Advantages

This 16 mm flat wood drill bit offers a balance of cutting diameter and reach for drilling medium-sized holes without the need for larger, heavier tooling. Its flat blade geometry enables efficient chip removal and stable drilling when used at correct feed rates. The bit is compatible with standard 3/8" or 1/2" chucks found on common power drills, making it suitable for on-site and workshop use. The design helps minimise tear-out on the exit face when proper backing and technique are applied.

Suitable for

• Drilling through-holes for cables and conduits in carpentry and joinery work
• Creating holes for dowels, bolts or fasteners in furniture assembly
• Installing electrical and plumbing runs through wooden studs and panels
• General-purpose drilling in softwood, hardwood, plywood and chipboard

Key specifications

• Cutting diameter: 16 mm
• Overall length: 160 mm
• Type: spade / flat wood drill bit
• Compatible with: hand drills and drill drivers with standard chucks
• Suitable materials: softwood, hardwood, plywood, chipboard

How to use

Secure the bit in the drill chuck and tighten firmly. Mark the drilling position and, if possible, support the workpiece with a backing board to reduce exit splintering. Start drilling at low to moderate speed to establish the hole, then apply steady pressure while allowing the bit to clear chips. Withdraw the bit periodically for deep holes to remove accumulated wood chips. For best results in hardwoods, use controlled feed and avoid excessive speed that can burn the cutting edges.

Usage recommendations

For cleaner exit holes, place a sacrificial backing board beneath the workpiece. When drilling long runs, pause occasionally to clear chips and inspect the bit for wear. Replace the bit if cutting edges become rounded or if drilling performance deteriorates.
