Enhancing Drilling Efficiency: The Modular Indexable Insert Drill
2024.10.08
The indexable insert drill is a modern and highly efficient drilling tool that replaces traditional solid drills with interchangeable polygonal blades. Designed to enhance productivity, reduce downtime, and lower drilling costs, these drills feature a unique design with a shaped central blade and peripheral blades using edge honing technology. This allows for doubled feed rates, high surface quality, and strict hole diameter tolerances. The design of these drills significantly improves productivity, reduces the processing cost per hole, and offers excellent cutting force balance, enhancing penetration rate, extending tool life, reducing hole tolerances, and improving surface quality.
These drills, commonly known as indexable insert drills or modular drills, are suitable for hole depths less than three times the hole diameter, but can also drill holes up to five times the diameter in cases of high tool stability. They are frequently used in automated equipment such as CNC machines, machining centers, and turret lathes.

Performance advantages include:
1. Increased chip space design: Maintains drill rigidity while increasing chip space for improved machining efficiency. Efficient chip removal is crucial during high metal removal rate operations to prevent chip congestion and drill damage. The optimized chip channels are particularly effective for long chip materials like steel and stainless steel.
2. Wide application range: Covers a diameter range of D14-D40mm, suitable for drilling operations of 3-5 times the diameter.
3. High-speed cutting: Suitable for high-speed cutting, with cutting speeds reaching 150-300 m/min when using coated blades.
4. Machining quality: High-quality machining with surface roughness values ranging from Ra=3.2 to 6.3 μm. H12-H13 hole tolerances ensure high dimensional accuracy.
5. Tool design: Special shape design with drill blades featuring 4 cutting edges for tighter hole tolerance control. High-strength fine-grained cemented carbide substrate with upgraded coating offers excellent wear resistance, toughness, and thermal stability.
6. Internal cooling structure: The drill shank incorporates an internal cooling structure to extend the life of the drill blades.
7. Versatility: In addition to drilling, can also be used for boring and countersinking.
