Flat Wood Drill Bit DeWalt 30 mm x 160 mm DT4830

DeWalt flat wood drill bit 30 mm x 160 mm DT4830 is a paddle-style bit engineered for creating clean, wide holes in soft and hardwoods. With a 30 mm cutting diameter and 160 mm overall length, this bit combines a sharp centering point and cutting spurs to provide accurate starts and reduced tear-out. It is compatible with standard hand drills and drill drivers, making it suitable for carpentry, joinery and installation work where fast, precise holemaking in timber is required.

Advantages

The flat wood drill bit delivers controlled cutting action thanks to its centering point, which ensures accurate positioning and reduces wandering at drill start. Cutting spurs produce clean hole edges and minimize splintering on both entry and exit surfaces. Its paddle shape and sturdy shank allow efficient chip evacuation and stable performance in hand-held drilling. The 160 mm overall length gives adequate reach for many common woodwork tasks while the 30 mm diameter accommodates large-through holes for fittings and conduits.

Suitable for

• Drilling holes for door hardware, locks and large fasteners in timber
• Creating openings for pipes and conduits in wooden panels and beams
• Carpentry and joinery tasks requiring clean, wide holes
• On-site installation work with hand drills or drill drivers

Key specifications

• Cutting diameter: 30 mm
• Overall length: 160 mm
• Type: paddle / flat wood drill bit
• Tip: centering point with cutting spurs for reduced tear-out
• Suitable materials: softwood and hardwood

How to use

Secure the bit in the drill chuck and tighten firmly before starting. Mark the required hole location and hold the workpiece steady or clamp it to prevent movement. Position the centering point on the mark, start drilling at low speed to ensure the point locates accurately, then increase speed as required while applying steady pressure. Withdraw the bit occasionally to clear chips when drilling deep holes, and finish drilling through to avoid splintering at the exit side. After use, clean chips from the bit and store it in a dry place.

Usage recommendations

Use appropriate personal protective equipment, including eye protection and hearing protection when required. For the cleanest edges, clamp a sacrificial backing board under the workpiece when drilling through thin or fragile panels. Avoid excessive side force to prevent bending the bit and maintain a straight, steady drilling motion.
