Gun Drill Bits - Deep hole capability: designed for long, straight holes with high accuracy in metal and other hard materials - Precision and straightness: tightly toleranced diameter with a rigid long shank to minimize deflection over extended lengths - Efficient cooling and chip removal: built in coolant channel delivers coolant directly to the tip and aids chip evacuation for reliable drilling - Durable construction: engineered for repeated use with consistent performance across long drill lengths - Compatibility: suitable for use in compatible drill presses or CNC machines that support gun drill geometry, with appropriate guiding tooling and coolant supply - Size and material options: available in a range of diameters and flute lengths; refer to product specs for material choice and length - Performance: maintains hole straightness and roundness with clean holes and minimal burrs Applications and use scenarios - Drilling deep holes in automotive shafts and housings where straight, accurate bores are required - Long bore holes in hydraulic cylinders and stainless steel tubes for precise component fit - Creating mold cores or precision cavities in aerospace and medical device manufacturing Note: Check exact size, material, and length options in the product specifications to select the right bit for your machine and application
