## Long description

DeWalt DT4650-QZ single drill bit with 30 mm diameter, overall length 380 mm and working length 280 mm. This replacement/standalone drill bit is manufactured for use in compatible rotary drills and chucks where a long reach and a wide bore are required. The tool is intended for drilling large holes in materials suitable for twist/auger-style bits of this design; it is supplied as a single piece for professional and DIY applications that demand a 30 mm cutting diameter and extended working length.
Advantages
The drill bit provides a wide 30 mm cutting diameter combined with a 280 mm working length, allowing deeper through-holes or recessed drilling without frequent tool changes. Its overall length of 380 mm gives extended reach for drilling into thick components or through assemblies. Supplied as one piece, the bit is ready to fit standard chucks that accept its shank type and size, reducing setup time on job sites. The design focuses on efficient material removal and stable cutting performance when used within the bit's intended application range.
Suitable for
 Creating large-diameter holes in wood and similar construction materials
 Drilling through thick panels, beams or floorboards where extended reach is needed
 Applications requiring a single long bit for deep or recessed drilling
Key specifications
 Cutting diameter: 30 mm
 Total length: 380 mm
 Working (usable) length: 280 mm
 Quantity: 1 piece
 Design: single straight drill bit for use in compatible chucks
How to use
Install the bit securely in a drill chuck compatible with the bit's shank, ensuring correct clamping and concentricity before operation. Select an appropriate drill speed and feed rate according to the material being drilled; reduce speed for harder materials and increase for softer materials like timber. Apply steady axial pressure without forcing the bit, clear chips periodically to prevent clogging, and allow the bit to cool if performing prolonged drilling sessions. Always follow the drill manufacturer’s instructions for safe operation.
Usage recommendations
Use appropriate personal protective equipment (eye protection, gloves, and hearing protection) and ensure the workpiece is secured. For best results in timber, start with a pilot hole if precise positioning is required, and remove chips frequently. Match drill speed and feed to the material to extend bit life and maintain hole quality.
