Spline Shank Bits- 2 Cutter & 4 Cutter - Makita

The Makita 711204-A Spline Shank Bit is engineered for professional technicians and mechanics requiring reliable drilling performance in challenging materials. This 2-cutter spline bit is designed to deliver efficient and precise drilling, making it an essential accessory for heavy-duty rotary hammers in demanding construction and industrial applications. Its robust construction ensures long-lasting durability and consistent performance on the job site.

Key Features

• High-Quality Tungsten Carbide Tips: Equipped with extra strong, high-quality tungsten carbide tips to ensure extended drilling life and superior resistance to wear.
• Optimized Flute Design: Features a symmetrical, double flute design that effectively reduces vibration during operation and maximizes dust removal for cleaner, more efficient drilling.
• Enhanced Torque Resistance: The bit's body is annealed to reduce internal tension, significantly increasing its resistance to torque and preventing breakage under strenuous use.
• Fast Drilling Performance: The 2-cutter design promotes faster drilling speeds, allowing professionals to complete tasks more quickly.
• Reinforced Construction: Modern brazing techniques ensure strong, heat-resistant joints, while a hardened shank provides additional durability against hammer blows.

Applications

These spline shank bits are specifically designed for use with rotary hammers that accept spline shank accessories, including Makita models such as the HR3851, HR4040C, and HR5000. They are ideal for drilling through a variety of tough materials, including reinforced and non-reinforced concrete, concrete block, and brick. Their precision engineering also makes them suitable for applications requiring accurate hole placement, such as anchor setting.
