MAXIMIZE DRILLING EFFICIENCY IN TOUGH METALS WITH SHOCKWAVE™ IMPACT TECHNOLOGY The Milwaukee 48-89-9252 set represents a critical advancement in accessory engineering, specifically designed to withstand the violent torque peaks of modern 1/4" hex impact drivers. By integrating a SHOCKZONE™ geometry into the shank, these bits absorb the stress that typically causes standard hex shanks to shear under load. The step bits feature a Titanium Aluminum Nitride (TiAlN) coating, which is superior to standard titanium coatings for heat dissipation, allowing for sustained drilling in stainless steel and other hard alloys without losing edge temper. For the twist bits, the RED HELIX™ design and Quad Edge tip minimize heat buildup while maximizing material removal rates, ensuring a professional-grade ROI through significantly extended tool life and reduced downtime on the jobsite. / SHOCKZONE™ geometry absorbs peak torque to prevent shank failure in high-impact drivers. / Titanium Aluminum Nitride (TiAlN) coating provides 5X longer life by managing extreme thermal loads. / Dual spiral flute design on step bits optimizes chip evacuation for 2X faster drilling speeds. / Rapid Strike Tip™ ensures precise starts without walking, even on curved or uneven surfaces. / Laser-engraved markings provide permanent size identification that won't wear off during heavy use.
