Holemaking Accessories – Enhancing Precision and Efficiency in Drilling Operations

In modern manufacturing, precision and process efficiency are essential to maintaining competitiveness and meeting high quality standards. Within drilling operations, Palbit’s holemaking accessories are engineered to optimize tool performance, reduce setup times, and provide greater flexibility in machining strategies.

These specialized accessories contribute to more reliable and streamlined production by improving dimensional control and minimizing downtime caused by frequent tool changes or manual adjustments.

 

CHAMFERING RINGS

               

CHAMFERING RINGS

Designed for streamlined workflows, these chamfering rings facilitate the simultaneous drilling and chamfering of workpieces. This dual-operation capability minimizes cycle times and lowers the tooling inventory required for hole preparation, contributing to improved efficiency and reduced machine downtime associated with tool changes.

Features:

  • Integrated on Drill: simultaneous hole drilling and chamfering in one operation
  • VBMT insert: the chipbreaker and grade should be specifically engineered to match the insert being used within the chamfering ring to ensure suitable workpiece machining
  • Versatility: compatible across all range of jet drills program

Mounting Procedure for Chamfering Rings

PROCEDURE 1

Slide the chamfering ring into the drill body and position it along the beggining of flute.

PROCEDURE 2

Ensure the chamfering ring is positioned to avoid obstructing chip flow and aligned with the flute.

PROCEDURE 3

Firmly tighten the chamfering ring, ensuring it is fully seated against the contour of the drill flange, then place the drill insert.

PROCEDURE 4

Correct instalation of the ring.

ECCENTRIC SLEEVES

               

ECCENTRIC SLEEVES

Palbit eccentric sleeves: a user-f riendly system that provides a versatile and effective solution accurate hole decentring and adjustable positioning. Their ingenious off-centre bore design allows precise micro-adjustment of drill positions, easily adapting to different requirements and tolerances. This cost-effective approach reduces the need for numerous f ixed-size parts by allowing adjustments for different effective diameters and minor misalignments , during drilling processes.

Features:

  • Fine diameter adjustment: slight drill axis shift for precise sizing
  • Adjustable hole decentering: enables fine-tuning of the bore’s offset from the intended center
  • MaxPro Drill: eccentric sleeve integration for offset capabilities

Mounting Procedure for Eccentric Sleeves

PROCEDURE 1

Align the adjustment markings perpendicular to the flat on the drill flange’s circumference.

PROCEDURE 2

Rotation of the sleeve is achieved through the hole on the eccentric flange.

PROCEDURE 3

Ensure the upper screw on the chuck is f irmly tightened against the Weldon flat of the drill.

PROCEDURE 4

Tighten the lower screw on the chuck just enough to contact the drill.
NOTES:
 
  • Reduce the feed rate by approximately 20% for 2D and 3D drills, and by 30% for 4D and 5D drills.
  • Designed for use with DIN 1835.
  • Not for use with lathe tools.
