El Costo Real de Equivocarse con Longitud Punta Broca

¿Cuánto le cuesta un número malo? Hagamos el cálculo en un escenario de taller. If your Longitud Punta Broca is 15% too aggressive, you're not just buying more YG-1 end mills — you're paying for unexpected downtime, rework, y missed delivery dates.

Annual Cost Breakdown
Premature Iscar tool failures$6,400/yr
Unplanned machine downtime$12,200/yr
Rework / scrap parts$8,700/yr
Excess Rego-Fix holder wear$2,100/yr
Total Annual Loss$29,400/yr

Now flip the scenario. By optimizing Longitud Punta Broca — using the manufacturer's recommended starting parameters for your specific YG-1 o Iscar tool, verified on a Mahr presetter — you could recover nearly $30K annually. That's a new DMG Mori tool probe o a year's worth of YG-1 inserts.

El ROI es inmediato. Primera pieza optimizada, primer día de ahorros.

Drill point length formula

The drill point length is the axial distance from the drill tip to the full diameter. It determines how deep you must drill past the required hole depth to achieve a full-diameter hole bottom.

Frequently asked questions

What is the standard drill point angle?

118° is the standard general-purpose point angle for drilling mild steel and cast iron. 135° is preferred for harder materials and is standard on most solid carbide drills. 140° is common for high-performance carbide drills in aerospace alloys.

Why does point length matter for CNC programming?

The drill must feed past the nominal hole depth by the point length plus a small clearance to achieve a full-diameter hole. For a 10 mm drill with 118° point, add approximately 3 mm to the programmed depth.

Can I use 135° drills in a 118° program?

No. A 135° point is shorter than a 118° point for the same diameter. If you switch without adjusting the depth, the hole bottom will be different. Always check the actual point geometry when changing drill brands.

How to use this Drill Point Length Calculator

Enter the drill diameter and point angle. The calculator gives the point length to add to your drilling depth and the approximate web thickness for reference. For through-holes, add point length + 2 mm clearance.
