Disston Company 442459 No. 3 Phillips Insert Bit 2 Pack

Product Description

The DISSTON COMPANY 442459 is a No. 3 Phillips insert bit tip sold in a 2-pack, designed for use with standard bit tip holders in power and hand screwdrivers. Each bit measures 1 inch in length and features a snub nose profile machined from shock-resistant tool steel. The short insert format allows for fast bit swaps without removing the holder from the tool, reducing downtime on the job. These bits are suited for electricians, HVAC technicians, plumbers, and general trades professionals who depend on consistent drive performance across repetitive fastening tasks.

The 442459 is well suited for residential and light commercial service work where No. 3 Phillips fasteners appear on equipment panels, junction boxes, access covers, and structural assemblies. The 1-inch insert length is compatible with standard quick-change bit tip holders used across cordless drills, impact-rated bit holders, and manual screwdrivers. The 2-pack format provides a backup bit on the bench or in the bag without the cost of a full set.

Key Features

• No. 3 Phillips tip profile for large-head fasteners common in trade applications
• 1-inch insert length fits standard bit tip holders for quick, tool-free changes
• Snub nose design reduces cam-out and extends service life
• Shock-resistant tool steel construction handles high-torque and impact use

Compatibility

Designed as an OEM-style insert bit for use with standard 1-inch bit tip holders compatible with most cordless and corded screwdrivers and drills accepting insert-style bits.

Installation Notes

Insert bits are installed and removed by hand into a compatible quick-change bit tip holder. Ensure the holder is fully seated and the bit is locked before applying torque. Inspect the bit tip for wear or rounding before each use, as a damaged tip increases the risk of fastener cam-out and head damage. No special tools or trade license is required to change insert bits.
