Dewalt DW1577 Spade Blade Drill Bit 11/16 Inch Hss

Product Description

The DEWALT DW1577 is a spade blade drill bit designed for fast, clean boring in wood and wood composite materials. Built from high-speed steel (HSS) with a bright polished finish, it measures 11/16 inch in cutting diameter and 6 inches in overall length. The 1/4 inch cylindrical shank seats securely in standard drill chucks and quick-change chuck systems. Electricians, carpenters, and plumbers routinely reach for spade bits when drilling through framing, blocking, and subflooring during rough-in work. The HSS construction handles repetitive use without rapid edge degradation under normal wood-boring conditions.

This bit is suited for residential and light commercial rough-in applications where 11/16 inch clearance holes are needed through dimensional lumber, engineered wood, and similar substrates. The 6 inch overall length provides enough reach for single-stud penetrations and shallow cross-members without requiring an extension. Electricians running wire through framing and plumbers routing supply lines through floor joists will find the 11/16 inch diameter a common working size for typical 1/2 inch pipe or conduit clearance applications.

Key Features

• 11/16 inch cutting diameter for common rough-in hole sizes
• High-speed steel construction for durable, repeated wood boring
• Bright polished finish with no coating buildup to interfere with chip clearance
• 1/4 inch cylindrical shank compatible with standard and quick-change drill chucks
• 6 inch overall length suits single-stud and shallow joist penetrations

Compatibility

Designed as an OEM-style spade blade drill bit fitting any 3-jaw or quick-change chuck that accepts a 1/4 inch cylindrical shank, including standard corded and cordless drills and drill drivers.

Installation Notes

Spade bits are installed and removed by hand or with a chuck key before the drill is powered. Ensure the drill is powered off and the trigger is locked out before changing bits. When boring through framing near electrical or plumbing lines, follow applicable NEC or IPC clearance requirements. Withdraw the bit periodically during deep cuts to clear chips and reduce heat buildup.
