uyarı
- U matkaplar torna tezgahında merkezin dışında kullanıldığında kolayca yanar.
- Küçük boyutlu bir U matkap kullanırken, yüksek hız ve yüksek ilerleme gereklidir. İlerleme ve hız ne kadar düşük olursa, kesme direnci o kadar yüksek olur ve takımın yanması o kadar kolay olur.

Optimized for deeper chipformer
Faster chip removal speed, which directly affects machining efficiency, deeper chip removal groove. Improvement in high feed and high speed, can still do not accumulate chips, not sticky insert, edge chamfer is smaller, optimize and improve the rigidity of the u drill body.
Precision design to inhibit insert wobble
Precise center and peripheral cutting edges can effectively inhibit oscillation when machining with uniform force; reduce the risk of tool bumping in difficult-to-machine material environments, and provide better accuracy/stability than general rapid drills.
Note: A insert with a peripheral edge cannot be used as a center edge; similarly, a center edge insert cannot be used as a peripheral edge; please be careful when replacing the edge.
Double screw oil hole high feed
The double helical oil holes protect the insert life and help to cool down the drill. The smaller the size of the rapid drill, the more important it is to follow a high RPM/high feed in order to minimize cutting resistance.

U drill machining common formula
（Data for reference only）
Cutting speed (Vc)
Vc= Dc*π*n/1000
- Dc(mm) :drill diameter
- Vc(m/min): cutting speed
- n(rev/min):rotating speed
Example
Spindle speed is 1600rev/min, the diameter of the drill is 20mm, the cutting speed is: Vc = Dc*π*n/1000 = 20*3.14*1600/1000 = 100 (m/min)
Feed speed (Vf)
Vf=Fr*n
- Vf(m/min):feed speed
- Fr(mm/rev):feed amount per revolution
- n(rev/min):spindle speed
Example
The spindle speed is 1350 min-1 and the drill diameter Ø12, find the cutting speed.
(Answer)
Substitute the formula
vf=f×n=0.2×1350=270mm/min
This gives the spindle feed per minute as 270mm/min.
Hole processing time(Tc)
Tc= ld*i/n*f
- Tc(min):machining time
- i:number of holes
- Fr(mm/rev):feed per revolution
- n(rev/min):spindle speed
- ld:drilling depth
Example
A hole Ø15, 30mm deep is drilled in SCM440 steel. The cutting speed is 50 m/min and the feed per revolution is 0.15 mm/rev. Find the drilling time.
(Answer)
Spindle speed n=(50×1000)÷(15×3.14)=1061.57min-1
Tc = (30 × 1) ÷ (1061.57 × 0.15) = 0.188
= 0.188 × 60 = 11.3 seconds to drill.
Metal removal rate(Q)
Q=Vc*Dc*Fn/4
- Vc(m/min):cutting speed
- Dc(mm):drill Diameter
- Fn(mm/r):feed

u drill processing power requirements
In order to truly utilize the machining effect of u drill, in addition to the toolholder and insert, you also need the right machine so that you can utilize the real machining ability of u drill.
Irregular surface drilling
Irregular
- Use shortest drill possible to minimize vibration tendencies and decrease the effects of deflection
- Recommended start values for cutting speed and lowest recommended feed
- Not recommended for 6–7×DC when concave radius is same or smaller than drill radius
Convex
- Use shortest drill possible to minimize vibration tendencies and decrease the effects of deflection
- Recommended start values for cutting speed and lowest recommended feed
- Not recommended for 6–7×DC when concave radius is same or smaller than drill radius
Concave
- Use shortest drill possible to minimize vibration tendencies and decrease the effects of deflection
- Recommended start values for cutting speed and lowest recommended feed
- Not recommended for 6–7×DC when concave radius is same or smaller than drill radius
Cross hole drilling
- For holes with different diameter: drill the larger hole first to reduce burr formation
- Start with lowest recommended feed during the crossing of holes
- Not recommended in long-chipping materials due to chip evacuation while crossing holes
Angled or inclined surfaces, entry
- Use shortest drill possible to minimize vibration tendencies and decrease the effects of deflection
- Start with lowest recommended cutting speed and 1/3 of lowest recommended feed (or lower) until fully engaged and then return to normal feed
- 4–5×DC the inclined entry can be angled up to 15º
- 6–7×DC the inclined entry can be angled up to 10º
Angled or inclined surfaces, exit
- Use shortest drill possible to minimize vibration tendencies and decrease the effects of deflection
- Recommended start values for cutting speed and lowest recommended feed (or lower)
- 4–5×DC the inclined exit can be angled up to 15º
- 6–7×DC the inclined exit can be angled up to 5º
Drilling asymmetrically curved surfaces
- Use shortest drill possible to minimize the drill bending outwards from the center, similar to an inclined surface
- Reduce feed to 1/3 of the initial penetration rate for a concave surfaces
- Radius of curved surface should be bigger than drill radius
- Not recommended for 6–7×DC drills
Pre-drilled holes
- To keep the cutting force balanced between the central and peripheral insert on an acceptable level, the pre-drilled hole should not be larger than DC/4
stack drilling
- Minimizing the gap between the stacked plates is crucial for successful stack drilling. This can be done by clamping or welding the plates together. A good common practice is to insert industrial paper (thickness of approx. 0.5-1 mm (0.020-0.039 inch)) between the plates to level out any irregularities and dampen vibrations. As the axial force will be several thousand newtons during the drilling process, the clamping supports are an important consideration.
