BIT SELF FEED 2"X5" CS

PRODUCT DESCRIPTION:

The Irwin Speedbor MAX #3046010 is a heavy-duty self-feed wood bit designed for making large, clean, through-holes in wood. It is part of Irwin’s “Speedbor MAX” line, meaning enhanced cutting edges, an aggressive feed screw, and other features optimized for fast, accurate drilling—especially when installing large boring tasks like plumbing, electrical conduit, or wood framing penetrations. The #3046010 has a 2-inch diameter, a 5-inch overall length, and uses a 7?16-inch quick-change hex/impact shank. It is built with high-speed steel or high-carbon steel and intended for frequent use in wood.

INSIGHTS:

Use in drills capable of delivering enough torque - cordless brushless or corded hammer / heavy duty drills are preferred.

Moderate drilling speed is better; feeding too fast causes burning, too slow causes binding. Withdraw the bit periodically to clear chips.

Secure the wood; use backing material to reduce tear-out on exit. Keep alignment straight.

Keep bit and screw tip clean from debris; occasionally clean and lightly oil to prevent rust.

In dense woods, wet woods, or in humid / hot conditions, extra care is required to avoid overheating.

Check if the screw point is replaceable; some packages come with spare feed screws.
