Disston Company 504720 Double Ended Insert Bit 2in

Product Description

The DISSTON COMPANY 504720 is a double-ended insert bit combining a No. 2 Phillips tip on one end and an 8-10 slotted tip on the other, measuring 2 inches in length. Built from shock-resistant tool steel, this insert bit is engineered for use with standard bit tip holders, allowing fast swaps without stopping work. The snub nose design extends service life by concentrating material at the working end, reducing breakage under torque load. This bit is suited for maintenance technicians, HVAC installers, electricians, and plumbers who drive fasteners regularly and need reliable, compact tooling in tight access areas.

This insert bit fits standard quick-change bit tip holders and magnetic bit extensions common across residential and light commercial jobsites. The dual-tip format reduces the need to carry two separate bits when a job involves both Phillips and slotted fasteners. It is well suited for panel work, equipment access covers, junction boxes, and mechanical equipment fastening where both drive types appear. The 2-inch length is the industry-standard insert size compatible with most bit holders and screw guns used in trade applications.

Installation Notes

Insert bits are installed and removed by hand into compatible bit holders — no tools required for the bit swap itself. Always ensure the bit is fully seated in the holder before applying torque to avoid slippage or tip damage. Inspect the bit for deformation or worn tips before each use, particularly when driving hardened or coated fasteners. Worn or chipped tips should be replaced immediately to prevent fastener head damage.
