Dewalt DW1927 Reduced Shank Drill Bit 27/64 in Hss

Product Description

The DEWALT DW1927 is a reduced shank drill bit designed for boring through metals and wood in professional trade and industrial applications. It carries a 27/64 inch cutting diameter with a 3/8 inch straight-cylindrical shank, allowing use in standard 3/8 inch chuck drills without requiring a larger machine. The bit is manufactured from high-speed steel with an oxide straw finish to resist heat and light surface corrosion during extended drilling operations. The 135-degree split-point tip reduces walking on entry, improving hole placement accuracy on metal surfaces. At 5 inches overall length with a 3.94 inch flute length, it provides adequate reach for most structural and mechanical drilling tasks.

This bit is suited for electricians, plumbers, HVAC technicians, and general contractors who need to drill through metal framing, conduit knockout positions, wood framing, or mechanical enclosures. The reduced shank design allows a larger cutting diameter to be driven by a standard 3/8 inch chuck tool, expanding capability without requiring a larger drill. Right-hand spiral flutes evacuate chips efficiently during through-hole operations in both metal and wood substrates.

Key Features

• 27/64 inch cutting diameter with a 3/8 inch reduced straight-cylindrical shank for use in standard chucks
• 135-degree pilot point tip reduces bit walking and improves entry accuracy on metal
• High-speed steel construction handles heat generated during metal drilling
• Oxide straw finish provides light heat and corrosion resistance
• 3.94 inch flute length maximizes drilling depth capacity relative to overall length
• Right-hand cut with regular spiral flutes for efficient chip evacuation

Compatibility

Designed for use in 3/8 inch chuck corded or cordless drills and drill presses; suitable for drilling metals and wood in residential and light commercial applications.

Installation Notes

This bit is installed and operated by electricians, plumbers, HVAC technicians, and general tradespeople using standard handheld or bench-mounted drills. Secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life. Wear proper eye protection when operating. Follow applicable NEC or OSHA guidelines for safe use of power tools on job sites.
