# Universal HSS Reinforced Carbon Brushes Replacement for Brushed Power Tools Boost your work stability and extend your power tool service life with these premium replacement brushes! ## Key Features 1. **Superior Wear Resistance**: Made of high-purity carbon blended with High Speed Steel (HSS), these brushes effectively reduce friction loss between the brush and commutator during long-term operation. Compared with standard pure carbon brushes, their service life is over 25% longer. 2. **Stable Current Conductivity**: HSS-infused carbon delivers consistent low-resistance current transmission, avoids power fluctuation, sudden shutdown or weak power output during operation, greatly improving your work efficiency. 3. **Fatigue-Resistant Durable Spring**: Equipped with high-elasticity copper spring, it maintains stable and appropriate pressure on the carbon block to ensure close contact with the commutator, eliminating sparking and unstable operation caused by poor contact. 4. **Anti-Corrosion Connection Terminal: High-purity brass terminal resists oxidation, rust and corrosion in dusty, humid or harsh construction working environments, reduces contact heat buildup and improves operation safety. 5. **Universal Precision Fit**: Precision cut with HSS reinforcing structure, it fits 152#/153# standard power tool installation slots perfectly, no extra modification required, supports fast and hassle-free replacement. 6. **High Load Temperature Resistance**: HSS reinforced carbon composition withstands high temperature generated by continuous high-load power tool operation, adapts to long-time continuous use for both industrial construction and home DIY projects. ## Specifications Material: Carbon + High Speed Steel Available Sizes: 303#-5*11*18mm, 21#-6.5*7.5*13.5mm, 43#-7*11*17mm, 103#-6*10*17mm, 153#-6.5*13.5*18mm, 50#-5*8*13mm, 411#-6*9*13mm, 6-100#-5*8*15mm Color: As pictured Quantity: 1 pair (packaging box style is random) ## Warm Tips 1.
