Drill bit YATO YT-3263 spiral 8 x 400 mm

Spiral drill bit YATO YT-3263 with an 8 mm diameter and 400 mm overall length is designed for long-reach drilling tasks. The straight-shank spiral geometry allows stable penetration and chip evacuation when working with compatible drill machines. This bit is intended for creating through or deep holes where an extended working length is required and fits standard chucks for straightforward installation.

Advantages

The long 400 mm length provides extended reach while the 8 mm diameter balances rigidity and access to narrow deep holes. Spiral flutes promote efficient chip removal and reduce the chance of clogging during continuous drilling. The straight-shank design ensures compatibility with most drill chucks and supports consistent concentricity and stable rotation under load. The bit construction is suitable for workshop and construction environments where deeper holes are needed without special extension accessories.

Suitable for

• Drilling through and blind holes in metal, wood, and some plastics when using appropriate speeds and feeds
• Accessing recessed or hard-to-reach drilling points in machinery and structural elements
• Workshop repairs, maintenance tasks, and on-site construction where extended reach is necessary
• Use with handheld and bench drills that accept an 8 mm shank

Key specifications

• Diameter: 8 mm
• Overall length: 400 mm
• Shank type: straight
• Flute style: spiral for chip evacuation
• Intended use: long-reach drilling for through or deep holes

How to use

Select a compatible drill machine and secure the spiral bit in the chuck, ensuring proper concentric clamping of the 8 mm shank. Choose cutting speed and feed rate appropriate to the material being drilled; reduce speed for harder metals and increase for wood or softer plastics. Apply steady pressure and allow the spiral flutes to evacuate chips—withdraw periodically on deep holes to clear swarf and reduce heat buildup. Use cutting fluid or lubrication when drilling metals to extend tool life and improve surface finish.

Usage recommendations

Inspect the bit before use and replace it when wear or damage is evident. For precise holes, run the drill at stable speed and avoid side loading. When drilling deep holes, clear chips frequently and use suitable coolant for metalwork. Store the bit in a dry place to prevent corrosion.
