Quick Spade Bit for Fast Wood Boring

The Timberline 604-650 is a 1-1/8 inch diameter spade bit designed for rapid, clean hole drilling in wood. Its micro-groove point and extended spurs reduce splintering while accelerating material removal. The bit suits tradespeople and DIY users who need efficient boring without frequent bit changes.

Fits Standard Drills with Quick-Release Chucks

A 1/4 inch quick-release hex shank locks securely into compatible drill chucks and impact drivers. The one-piece forged construction eliminates a separate shank joint, so the bit runs true and transfers torque directly. Heat-treated tool steel resists wear during repetitive drilling tasks.

Single Bit Optimised for Speed and Durability

No additional accessories or software are included with this accessory. The forged, heat-treated body and precision-ground cutting edges are the only features that affect performance. Buyers needing multiple diameters or a storage case must source those separately.

Questions about this item

How long can I bore continuously before the heat-treated steel dulls?

The bit is forged in one piece from special-grade tool steel and heat-treated for extra strength, so it resists wear during extended drilling sessions.

Does the bit generate noticeable vibration or heat during all-day use?

Micro-groove point and extended spurs produce faster, cleaner boring action, reducing friction and vibration even in prolonged operation.

What drill chuck is required for the 1/4 quick-release hex shank?

A 1/4-inch quick-change hex chuck or impact-ready driver accepts the shank directly for instant bit changes.
