Deep Hole Drilling Heads with Upgraded Features


DEEP DRILL

Highlights
ISCAR-UNITAC is introducing upgraded features for the FINEBEAM family of deep hole drills


The FINEBEAM line’s upgraded features include:
  • Tool improvement
  • Expansion of the diameter range
  • Expanded variety of inserts
  • Updated insert description


Tool improvement features (compared with the former drilling heads version)
  • Guide pad protector: to prevent pad breakage during retraction
  • Tighter tolerance of the pilot thread: to increase the contact between the head and the tube, and help avoid separation of the head during retraction
  • Higher hardness and screw length: to increase and stabilize the clamping feature



  1. Steel bump added on the body behind each guide pad
  • Prevents guide pad breakage while retracting through hole/cross-hole
    2. Updated pilot tolerance
    • Prevents the body pull-out while machine stops
    3. High grade screw
    • Tougher and longer screw to increase clamping reliability



    Expansion of FINEBEAM – Ø65.01-83.00 mm range

    Based on market demand and success of our existing range (Ø25.00 - 65.00), ISCAR-UNITAC is expanding the FINEBEAM range from Ø65.01 to 83.00 mm for deep hole drilling operation, with existing inserts and spare parts.

    Advantages of 5 direct mounting inserts compared to existing solutions in this diameter range:
    • Smaller chips – to ensure good chip control and chip evacuation
    • Lower machine consumption
    • No cartridges – lower tool cost
    • Stable and simple insert mounting

    New HF (high feed) chip breaker
    BTA drill series has expanded the variety of inserts available with a new HF chipbreaker insert in IC806 and IC908 grades and new radius size of 0.8mm.

    The new radius size also applies for “G” type chip breaker.
    The expansion should significantly improve FINEBEAM performance, which should increase the feed by 20% in average in machining gummy materials, stainless steel and heat-resistant alloys, known as problematic materials in terms of chip formation.

    The HF chip breaker helps to stabilize the drilling process while using high feed, especially in difficult to machine materials such as ISO-M, ISO-S and ISO-H materials.
