Side Locking Indexable Crown Drill for Metal Stainless Steel
Bullet Points
Side Locking Stable Structure：Adopts integrated side locking clamping design, no screw loosening problem. It effectively solves the defects of easy vibration and low precision of traditional screw drills during long-time deep hole processing, ensuring high stability of hole roundness and smooth surface finish.
Indexable & Replaceable Inserts：Equipped with universal standard carbide inserts, support multi-angle indexing and quick replacement. No need to regrind the drill body, greatly reduce tool replacement cost and downtime, improve production efficiency for mass processing.
3D Internal Cooling Design：Built-in three-dimensional coolant channel, directly delivers cutting fluid to the cutting area. Realize rapid heat dissipation and smooth chip removal, effectively avoid tool burning and workpiece burrs, suitable for continuous high-load machining.
High Rigidity & High Precision：The drill body is made of high-strength alloy steel with integral quenching treatment. The radial runout is controlled within 0.02mm, with high overall rigidity, no tool deflection, ensuring consistent hole tolerance.
Wide Compatibility & Customization：Multiple depth ratios of 1.5D/3D/5D/8D are available, standard diameter range 12mm-40mm. Support custom size and special shank to match different CNC machining centers and lathes.
Applications
Suitable for drilling and deep hole processing of carbon steel, alloy steel, stainless steel, cast iron and aluminum alloy. Widely applied in automotive parts, mold manufacturing, mechanical equipment, engineering machinery and aerospace industry, compatible with CNC machining centers and CNC lathes.
Hot Q&A
- What is the biggest advantage of side locking structure?
Answer: The side locking structure realizes integral clamping without independent locking screws. It avoids screw loosening, thread slipping and tool vibration during high-speed cutting. It features higher stability, longer service life and lower failure rate than traditional screw-type crown drills.
- Are your carbide inserts compatible with mainstream brands?
Answer: Yes. Our indexable inserts are fully compatible with mainstream 880 series standard inserts on the market. Customers can replace inserts directly without changing the drill body, which saves procurement time and cost.
- What depth ratios do you support?
Answer: We provide standard 1.5D, 3D, 5D, 8D deep hole drills. Customized deeper depth and special size are acceptable according to customer drawings.
- Can this drill process stainless steel?
Answer: Definitely yes. The TiAlN coated carbide inserts have excellent heat resistance and wear resistance. The internal cooling design ensures smooth chip removal, which is very suitable for stainless steel, high-hardness steel and difficult-to-cut materials.
