Product Description The GT Tools Medium Round Tip Drill Bits are professional-grade tungsten carbide cutting tools engineered specifically for automotive glass repair preparation. Featuring a smooth, rounded tip profile, these bits allow technicians to cleanly open access channels into tight surface breaks, star chips, and bullseyes while minimizing the overall impact footprint on the outer layer of laminated glass. In professional shop environments, proper damage site preparation is critical to the entire windshield repair workflow. By drilling a shallow, controlled entry point, technicians relieve surface tension and create a clear pathway for repair resin to penetrate deep into the break. For body shops across Canada expanding into auto glass restoration, these highly durable bits ensure clean, consistent cuts that prevent secondary micro-cracking and support structurally sound repairs. Key Features Precision Round Tip Profile: Specifically shaped for shallow surface drilling to create a smooth, controlled access point without causing unnecessary chipping or flaking. Tungsten Carbide Construction: Manufactured from premium hardened steel and tungsten carbide to maintain a sharp, reliable cutting edge against hard automotive glass. Consistent Service Life: Engineered to reliably complete approximately 5 to 10 windshield repairs per bit, depending on operational speeds and drilling technique. Universal Tool Compatibility: Standardized shank dimensions fit securely into GT Tools cordless drills, 12V rotary tools, and standard auto glass repair collets. Workflow Efficiency: Enables rapid preparation of impact sites, allowing technicians to transition smoothly to the bridge mounting and resin injection stages. Ideal For Windshield Repair Specialists: Opening access channels to tight star breaks and multi-point stone chips prior to injection setup. Collision Repair Facilities: Integrating reliable glass preparation into standard repair, structural, and detailing workflows. Mobile Auto Glass Technicians: Maintaining dependable, compact cutting consumables for consistent field performance in varying temperatures. Common Questions Q: When should a round tip drill bit be selected over a tapered tip? A: A round tip bit is designed for shallow surface drilling to create a slightly wider, smooth entry point for resin, whereas tapered bits are typically selected for deeper, pinpoint penetration into tight center impacts. Q: What is the expected lifespan of a single carbide bit? A: Under standard daily usage in Canadian collision repair shops, each bit is engineered to perform cleanly for approximately 5 to 10 complete windshield repairs before requiring replacement. Q: What operating speed is recommended for drilling automotive glass? A: To maximize bit longevity and prevent excessive friction heat that can crack laminated glass, technicians should operate their rotary drills at low to medium speeds while applying gentle, pulsing pressure.
