The 135° quick-cut pilot split points are self-centering and can penetrate quickly with less pressure. The straight shank allows for firm holding and accurate centering, making the drilling process precise and faster. 3. The fully ground spiral groove design clears particles quickly, decreases friction and heat, resulting in faster drilling performance. 4. These drill bits are perfectly suitable for drilling holes in Stainless Steel, Copper, Cast Iron, Galvanized Pipe, Aluminum Alloy, Wood, and other softer metals. They are not recommended for use on Glass or Ceramic materials. 5. The drill bits fit the majority of power drills currently on the market and come with a portable plastic case for easy storage, DIY, household maintenance, and repair.

Instructions for Use: 1. Keep the drill bits vertical to the object when drilling, and ensure both the bit and work piece are stable. Tilted bits are prone to breaking during drilling. 2. Control the speed and pressure when using the bits with a power drill. It is recommended to use them at low speed and drilling pressure. 3. Drilling metal will generate heat. It is necessary to use a cooling liquid during drilling to keep the bit cool. 4. Thick metals are recommended to be drilled with a drill press, as it is more stable and adjustable.

Safety Instructions: 1. Always wear safety goggles and other safety items when drilling. 2. Do not wear gloves to avoid the hazard of getting caught in the tool and pulling your hand into the spinning bit. 3. Examine the bits before use for cracks or chips, and do not use damaged or dull bits.
