Stanley 30884VB4 Variable Bit Set 3/16 to 1/2 Inch

Product Description

The STANLEY 30884VB4 is a variable bit set covering a size range of 3/16 inch to 1/2 inch, designed for drilling fast, clean, round holes in trade and industrial applications. The patented two-flute design drives through material efficiently while the split point tip starts on contact, reducing walking and the need for a center punch. A steam oxide coating increases surface durability. This set is suited for electricians, plumbers, HVAC techs, and other trade professionals who need reliable, repeatable hole quality in wood, composite, or similar substrates.

The 30884VB4 variable bit set is appropriate for residential and light commercial work where a range of hole sizes is required without changing tools. The 3/16 inch to 1/2 inch range covers common trade applications such as wire and conduit pass-throughs, pipe penetrations, and bracket mounting points. An enhanced flute geometry evacuates chips rapidly, keeping the cutting edge clear and reducing heat buildup during extended use. LENOX PROTOOL Lube is recommended to extend bit life when drilling harder materials or in high-volume production scenarios.

Key Features

• Patented two-flute design produces fast, clean, round holes
• Split point tip reduces walking and eliminates the need for a center punch in most applications
• Steam oxide coating improves surface durability and corrosion resistance
• Enhanced flute geometry evacuates chips rapidly to reduce heat and bit wear
• Variable size range from 3/16 inch to 1/2 inch in a single set

Compatibility

Designed as an OEM-style replacement or direct-use variable bit set compatible with standard drill chucks accepting shank sizes in the 3/16 inch to 1/2 inch range.

Installation Notes

Secure the bit firmly in a compatible drill chuck before use and verify the chuck is fully tightened. Power down the drill before changing bits or adjusting the size setting. Follow applicable safety codes and wear appropriate eye protection when drilling. Apply LENOX PROTOOL Lube as directed to maximize bit life, particularly during high-volume or continuous drilling operations.
