BIT DRILL SPADE 1/2"X 4"

PRODUCT DESCRIPTION:

The Master Mechanic 158843 Stubby Spade Bit is a compact wood-boring bit designed for use in tight or shallow spaces where a standard spade bit would be too long. The “stubby” design (shorter length) helps reduce flex, wobble, and binding in constrained areas.

INSIGHTS:

Drill with Proper Support - When drilling, clamp the wood securely and back up the exit side to reduce tear-out, especially near the end of the hole.

Use Moderate Speed / Pressure -Use moderate drill speed and gentle, steady feed pressure. Avoid pushing too hard, which can cause bit deflection or chatter.

Sharpen / Maintain Spurs - The cutting spurs are important for clean edges — keep them sharp and free of nicks. When resharpening, preserve the spur angle to maintain performance.

Chip Clearing - In deeper holes (though this bit is shallow-only), retract periodically to clear chips and avoid binding.

Storage & Rust Prevention - As with most bits, keep it clean and dry. Wipe off sap, moisture, and store in a protected place to prevent corrosion.
