High-performance materials: made from durable carbon and copper to improve wear resistance and ensure efficient power transfer during operation. These materials reduce heat and electrical loss for more reliable tool performance. Multiple sizes/types available: choose from four options (Type 1 to Type 4) to match different tool designs and service needs. Having the right type helps ensure correct fit and consistent electrical contact. Cross-model compatibility: designed for use with a wide range of electric drills and hammer drills, including the 6343DWDE model. Compatible across models to simplify parts sourcing and repairs. Function and benefit: these components restore or maintain stable motor performance by providing consistent electrical contact and reduced arcing. They solve common problems such as intermittent power, reduced torque, and premature wear. Easy replacement and maintenance: standard form factors allow quick swaps during routine service, minimizing downtime for both home users and professionals. Performance highlights: improved durability, stable current flow, and better overall tool efficiency compared with worn or degraded components. Practical applications Home DIY repairs: replace worn components in your household drill to regain consistent power and extend the life of the tool for tasks like assembling furniture, drilling anchors, or installing fixtures. Professional jobsite use: keep spare types on-site for fast replacement in construction, renovation, or electrical work where tool reliability and uptime matter. Workshop maintenance: ideal for routine servicing of power tools in a repair shop or maintenance department to prevent failures and maintain consistent performance across multiple tool models. Compatibility notes Available in Type 1 through Type 4—select the correct type for your specific tool model. Confirm compatibility with your drill or hammer model; specifically noted as compatible with the 6343DWDE and other similar electric drills and hammers. What you get Robust carbon-copper construction for longer service life and efficient power transfer. Four type options to match different tool requirements. Parts designed for cross-model use to simplify repairs and reduce parts inventory.
