Dewalt DW1607 1/4 in Mechanics Drill Bit 135 Degree Hss

Product Description

The DEWALT DW1607 is a 1/4 inch mechanics drill bit designed for heavy-duty drilling applications in wood and similar workpiece materials. Built from high-speed steel with an oxide finish, it features a 135-degree split point that self-centers on contact, reducing walking and the need for a center punch. The web-thinned, tapered web construction reduces cutting resistance and improves chip evacuation. The straight-cylindrical shank measures 1/4 inch in diameter and seats securely in standard drill chucks. Overall length is 6 inches, with a flute length and maximum drilling depth of 2.83 inches. Right-hand cut with a regular spiral flute pattern completes the geometry.

This bit is suited for residential and light commercial work where a reliable, fast-cutting mechanics bit is needed. Typical applications include drilling through wood framing, rough carpentry, and general mechanical assembly tasks. The 135-degree split point geometry makes it particularly well-suited for starting holes without a pilot or center punch, improving workflow on repetitive drilling tasks. Trades commonly reaching for this bit include carpenters, general contractors, HVAC mechanics, and electricians drilling through wood framing during rough-in work.

Key Features

• 135-degree split point tip self-centers and reduces bit walking on entry
• High-speed steel construction handles heavy-duty drilling demands
• Oxide finish provides corrosion resistance and reduces friction during cutting
• Web-thinned tapered web reduces feed force and improves chip clearance
• 1/4 inch straight-cylindrical shank with 3 flats fits standard drill chucks securely
• 6 inch overall length with 2.83 inch maximum drilling depth suits most framing and assembly tasks

Compatibility

Designed as an OEM-style replacement mechanics drill bit for use in standard 3-jaw drill chucks and quick-change chuck systems accepting 1/4 inch straight-cylindrical shanks. Primary workpiece material is wood.

Installation Notes

This bit is installed and changed by any trade professional using a standard keyed or keyless drill chuck. Ensure the drill is powered off and unplugged or the battery removed before changing bits. Secure the shank fully in the chuck and verify tightness before beginning work. Wear appropriate eye protection when drilling, as chip ejection direction is determined by right-hand cut spiral flutes.
