Milwaukee 48-27-0170 Flat Boring Drill Bit 3/8 in Hex Shank

Product Description

The MILWAUKEE 48-27-0170 is a flat boring drill bit engineered for wood boring applications in residential and commercial construction. It features a 3/8-inch drill diameter with a spur point tip that scores the wood fibers before the main cutting edge engages, producing cleaner hole entry and exit. The 1/4-inch hex shank seats securely in standard quick-change chuck systems, eliminating bit slippage under load. At 16 inches overall length, this bit reaches through thick framing members and stacked materials without requiring an extension. Electricians, plumbers, and general carpenters rely on this style of bit for drilling wire and pipe passages through wood framing.

This flat boring bit is suited for drilling through dimensional lumber, engineered wood products, and wood framing in rough-in work. The extended 16-inch length makes it practical for drilling through double or triple framing members and other deep-stack wood assemblies. The hex shank is compatible with standard 1/4-inch quick-change bit holders and most cordless drill and driver chucks equipped for hex shanks. It is commonly used by electricians and plumbers during rough-in phases where wire or pipe must pass through wood framing.
