Advantage
Ultra-Low Comprehensive Machining Cost The U indexable drill features a split structure of durable steel drill body and replaceable carbide inserts. There is no need to replace the entire drill after wear or damage. Only the consumable inserts need to be updated, which greatly reduces long-term tool procurement costs and workshop operating expenses compared with solid carbide drills and twist drills.
Super High Drilling Efficiency for Mass Production Also known as U drill, quick drill or violent drill, it supports high-speed and high-feed one-shot drilling. It completes hole forming in a single pass without pre-drilling or repeated trimming, greatly shortening processing cycles and significantly improving production efficiency for large-batch metal hole processing.
Built-In Internal Cooling Design for Stable Cutting Equipped with standard internal coolant holes, the U indexable drill delivers cutting fluid directly to the cutting edge during operation. It effectively reduces high cutting temperature, eliminates built-up edge, reduces tool wear, and adapts to long-time continuous heavy cutting of stainless steel, alloy steel and hard metals.
High Rigidity & Precision Hole Machining Effect The drill body adopts high-strength alloy steel with overall quenching treatment, featuring high rigidity and excellent anti-vibration performance. It effectively avoids hole deviation, dimensional errors and surface burrs, ensuring high-precision hole tolerance and smooth inner wall finish for finished workpieces.
Wide Material & Equipment Compatibility Versatile for multiple metal materials including carbon steel, stainless steel, mold steel, cast iron and aluminum alloy. It is perfectly compatible with CNC machining centers, CNC lathes and milling machines, widely used in auto parts, mechanical hardware, mold manufacturing and engineering machinery processing industries.
Simple Operation & Fast Insert Replacement The optimized precise clamping structure enables quick disassembly and replacement of carbide inserts without complex tools. It greatly saves tool change time, reduces equipment idle time and improves the overall operation efficiency of the processing workshop.
Durable Drill Body & Long Service Life The heat-treated steel drill body is wear-resistant, impact-resistant and not easy to damage in daily processing. Only low-cost inserts are consumed regularly, which extends the service life of the main tool body and reduces frequent tool replacement and debugging costs.
FAQ
Q: What is a U Indexable Drill?
A: U Indexable Drill (U drill) is a high-efficiency CNC indexable hole-making tool. It is specially designed for rapid drilling, shallow hole machining and step hole processing of metal workpieces, and is the mainstream efficient drilling tool for industrial mass production.
Q: What materials can U indexable drills process?
A: It is suitable for most common industrial metals, including carbon steel, stainless steel, alloy steel, mold steel, cast iron and aluminum alloy. By matching different coated inserts, it can adapt to high-hardness metal and high-precision finishing processing requirements.
Q: What are the advantages of U indexable drill over traditional twist drill?
A: Different from traditional twist drills that are easy to wear, burn and need overall replacement, U indexable drills support high-feed high-speed drilling with higher efficiency. It has better cooling performance, lower comprehensive cost, more stable precision and is more suitable for large-diameter and mass drilling processing.
Q: What do 2D, 3D, 4D and 5D mean for U drills?
A: The letter D refers to the drill diameter, representing the maximum drilling depth multiple. 2D/3D U drills are for ultra-efficient shallow hole processing, while 4D/5D models are used for medium and deep hole drilling to meet different depth machining requirements.
Q: Can U indexable drills process deep holes?
A: Yes. Standard 2D to 5D U indexable drills can cover most shallow and medium-deep hole processing scenarios. For ultra-deep hole machining, we can provide customized models and professional cutting parameter suggestions.
Q: Do you offer custom U indexable drills?
A: Yes. We support customized shank types, drill body specifications, special drilling depths and non-standard structures. We can also select matching inserts and customize coatings according to your processing materials and machine tools.
Q: How to maintain and extend U drill service life?
A: It is recommended to adopt reasonable cutting speed and feed rate, ensure sufficient internal coolant supply to avoid dry cutting and overload machining. Regularly check the insert clamping tightness to reduce vibration and prevent edge chipping during processing.
