Today, I’d like to talk to you about a type of cutting tool that’s very commonly used in workshops— Indexable U drill Many customers are encountering this for the first time. You U Every time we drill, we always ask: “Just what makes it better than a regular drill bit?”
Simply put, if you often process... 12mm For the above-mentioned apertures, if you require higher efficiency, longer service life, and processing of complex materials, then... You U Drilling is virtually irreplaceable.
I. Why use it? You U Drilling? Because it makes drilling fast and stable.
Compared to solid carbide drill bits, You U The advantages of drilling are very clear:
Large cutting depth, high efficiency
One single cut can remove a larger volume of metal, making it particularly suitable for large-hole machining of steel parts, stainless steel, and alloy steel.
Replaceable blades, lower cost
If the blade wears out, you can simply replace the blade instead of the entire tool, making it more suitable for mass production.
Tool life is stable.
The blade edge boasts high strength and excellent chipping resistance, allowing it to perform reliably even on hardened steel, alloy steel, and even titanium alloys.
Chip removal is smooth and holes are not easily clogged.
You U Drills are inherently equipped with wide flutes and ample chip evacuation space, making them less likely to get "stuck" during continuous deep-hole machining and reducing downtime for chip removal.
These characteristics make it so that... You U Drills have become the standard cutting tool for many workshops when drilling on CNC lathes, machining centers, and turn-mill-turn machines.
II. Square You U Drill vs. Peach-shaped You U Drilling: Two Structures, Two Advantages
Lizhou You U There are two commonly used drill structures: square blades. You U Drill and peach-shaped blade You U Drill.
They’re not about who’s better or worse—rather, they’re each doing their own thing:
Square You U Drill (Strength Faction)
The blade has high rigidity.
Very high stability
Excellent chip-breaking capability
Suitable for heavy-duty machining of ordinary steel parts, cast iron, and alloy steel.
Peach-shaped You U Drill (Precision Class)
Good stability performance
Cutting is light and nimble.
Chip removal speed is faster.
More suitable for small apertures You U Drilling and Deep Hole Machining
Particularly effective for stainless steel and titanium alloys.
3. Wide range of compatible materials—can process everything from steel parts to titanium alloys.
You U The drill blades feature a indexable design. LiZhou will provide different blade grades tailored to various materials, suitable for:
Drilling steel parts ( 45# 、40Cr、 42CrMo Wait)
Stainless steel drilling ( 304、316 Materials that are easy to stick to the blade)
Hardened steel drilling
Aluminum alloy drilling
Drilling of titanium alloys and high-temperature alloys
Especially when it comes to “difficult-to-handle” materials such as stainless steel and titanium alloys, You U Drills are more chip-resistant and stable than solid blades.
4. Drill, bore, and chamfer—all in one tool. You U Drilling can handle more processes.
Many customers tend to overlook it. You U One hidden advantage of drilling:
You U Drills can not only drill holes, but also bore, ream, and even chamfer directly.
This means:
One knife handles three processes.
Reduced number of workpiece clamping operations
Overall processing cycle improved
The hole has better consistency (because there’s no tool change and no repeated positioning).
For mass production, this is a real advantage that can significantly improve efficiency and reduce costs.
Five, Lizhou You U A few “real advantages” of drilling
We don’t talk about empty rhetoric—only about what you can truly feel on the machine tool:
1. Rigid foot—no shaking when cutting.
The blade body is designed with high-strength steel, featuring an earthquake-resistant structure that allows the machine tool to "boldly push the blade forward."
2. Chip removal is smooth and trouble-free—no worries even with deep holes.
The groove is wide and chip removal is smooth, so even deep holes in stainless steel are unlikely to get clogged with chips.
3. Plenty of blade options—no problem even with tough materials!
Steel parts, cast iron, stainless steel, titanium alloys, and non-ferrous metals each have corresponding grade designations.
4. Long lifespan, doesn't pick machine tools.
Whether it's a machining center or a conventional CNC lathe, as long as the parameters are set appropriately, the tool life can be fairly predictable.
5. Low replacement cost
Simply replace the blade after it wears out—especially suitable for multi-shift production.
Six, why can Lizhou do it? You U Are you done drilling?
Select high-quality cemented carbide blade materials.
The blade body features a reinforced design for impact resistance.
Each set You U All drills undergo rigorous vibration and precision testing.
The blade and blade body fit closely together, enhancing stability.
The internal cooling hole layout is scientifically designed to ensure that the coolant reaches the cutting edge directly.
Whether you choose a square blade or a peach-shaped blade, Lizhou can provide you with stable machining performance.
Conclusion: You U Drilling isn't a panacea, but it's the fastest way to drill large holes.
If your workshop does the following every day:
Ø12 – Ø50mm the hole
Batch drilling of steel parts, stainless steel, and hardened materials
Processes with requirements for efficiency and lifespan
So then You U Drills made of cemented carbide are more cost-effective and hassle-free than solid carbide drills.
If you tell us your material, aperture, depth, and machine tool type, we can recommend a suitable one for you on-site. You U The drill model and blade grade ensure easy cutting by the machine tool and more stable hole machining.
Lizhou isn't just about selling cutting tools—it's your trusted partner in machining and cutting operations.
