Why the Four-Facet Split Point Improves Your Drilling Accuracy

At first glance, a drill point might look simple, but the four-facet split point is actually a clever design twist. Think of it like the difference between trying to draw a perfect circle freehand versus using a compass. The split point design helps the drill bite into the material more precisely right from the start. It reduces the tendency for the drill to wander or 'walk' when you begin drilling, meaning your holes start exactly where you want them. This helps avoid mistakes, saves time on touch-ups, and results in cleaner, more accurate holes, especially in tricky metals.

Installation and Maintenance Guide

Setting It Up

  • Ensure the drill chuck matches the 10.30 mm shank diameter for a secure fit.
  • Clean the drill and chuck before installation to avoid debris interfering with grip.
  • Tighten the chuck firmly but not overly tight to prevent shank damage.
  • Set drill speed according to metal type; slower speeds for harder metals.
  • Use cutting fluid or coolant when drilling to extend tool life and reduce heat.

Keeping It Going

  • Regularly inspect the drill tip for wear or dullness.
  • Sharpen the drill promptly to maintain cutting efficiency.
  • Clean flutes after use to prevent material buildup and clogging.
  • Store in a dry place to avoid corrosion or rusting.
  • Replace the drill if you notice chipping or significant damage to the cutting edges.

Buying Guide: Choosing the Right Standard Jobber Drill

  • Need help choosing the right size? Consider the material thickness and hole diameter before Selecting your drill size.
  • Not sure between standard cut and double cut? Standard cut offers fast drilling with good chip removal, while double cut gives a smoother finish on tougher materials.
  • Wondering about drill point angles? A 118-degree split point is best for general-purpose metal drilling and reduces walking.
  • Looking for durability? Carbide tips are harder and last longer but require correct speeds to avoid damage.
  • Think about drill length? Longer drills reach deeper but can flex under pressure—choose based on your project needs.
  • Need to maximize precision? Tight tolerance drills (+.000/-.0005) help ensure exact hole dimensions.

Frequently Asked Questions

  • Q: What materials are these Carbide Jobber Drills best suited for?

    A: They are primarily designed for drilling metals but can work on various other hard materials.

  • Q: What is the benefit of the four-facet split point?

    A: It reduces walking and improves precision during drilling start-up.

  • Q: Can I use these drills in a hand drill, or only CNC machines?

    A: They can be used in both, but always ensure proper speed and support to avoid breakage.

  • Q: How do I know if I should choose the standard cut or double cut version?

    A: Standard cuts are great for general-purpose metal drilling, while double cuts provide smoother finishes on hard materials.

  • Q: What drill speed is recommended for these Carbide Jobber Drills?

    A: Speeds vary by material, but generally slower speeds prevent overheating of carbide tips.

  • Q: Are these drills resistant to heat buildup?

    A: Carbide material handles heat better than high-speed steel, but cooling fluid helps maximize drill life.

  • Q: What is the maximum depth I can drill with this tool?

    A: The flute length is 73 mm, so optimal drilling depth is within that range for effective chip removal.

  • Q: How tight is the diameter tolerance on these drills?

    A: The tolerance is tightly controlled to +.000/-.0005 for precise hole sizes.

  • Q: How do I know when it’s time to Replace or Resharpen the burr?

    Replace or Resharpen it when you notice decreased cutting efficiency or visible wear on the cutting edges.
