Product Description

Product Description

Drill Bit: Essential Cutting Tool for Precision Hole-Making

A drill bit is a rotating cutting tool designed to create holes in various materials, including metal, wood, plastic, and concrete. Characterized by its sharp,spiral - shaped (helical) cutting edges, it is widely used in machining, construction, woodworking, and DIY projects.
Key Features & Types
Cutting Edge Design: The tip of a drill bit features flutes (spiral grooves) that channel chips away from the hole during drilling, reducing friction and preventing clogging. Common tip styles include twist drills (most versatile), spade drills (for large holes in wood), and masonry bits (with carbide tips for concrete/stone).
Material Compatibility: Drill bits are crafted from high-speed steel (HSS) for general use, cobalt steel for hard metals (e.g., stainless steel), carbide-tipped for durability, or diamond-coated for extreme hardness (e.g., glass, ceramics).
Shank Types: The shank (non-cutting end) connects to a drill chuck. Hexagonal shanks prevent slipping, while round shanks suit standard chucks. SDS shanks are specialized for hammer drills, enhancing power transmission.

Applications

From drilling pilot holes in metal fabrication to creating anchor holes in construction, drill bits are indispensable. In CNC machining, precision drill bits ensure tight tolerances, while in woodworking, brad point bits deliver clean, splinter-free holes.

Main Technical Parameters

Select the right drill bit parameters for a workpiece material

Focus on matching the bit's design to the material's key properties

Hard materials (e.g., stainless steel, cast iron): Choose carbide or HSS-Co bits with a 135° split point (for precise entry) and TiAlN/TiCN coatings (enhanced wear resistance). Use low feed rates and moderate-to-high speeds, with cutting fluid to reduce heat.
Soft materials (e.g., aluminum, copper): Opt for HSS or carbide bits with a 90°–118° point angle, large helix angle (for efficient chip evacuation), and polished or DLC-coated edges (to prevent adhesion). Use high speeds, moderate feed rates, and kerosene or air cooling.
Composites (e.g., CFRP/GFRP): Select diamond-coated or PCD bits with a double-point angle (to minimize delamination). Use low speeds, high feed rates, and air cooling to avoid fiber damage.
Always prioritize compatibility between the bit's material, coating, geometry, and the workpiece's hardness, toughness, and chip-forming characteristics.
