Precision drill jig bushings and liner sleeves represent critical guiding components for metal drilling and reaming fixtures, engineered to eliminate drill bit wander and maintain exact hole coordinates. Manufactured from high-grade alloy or bearing steels and heat-treated to a high hardness rating, these bushings withstand the severe frictional contact of rotating cutting tools without wearing out. The precision-ground interior bore guides the drill bit directly into the workpiece, while the outer diameter fits securely into the jig plate or liner sleeve. Produced under rigorous dimensional standards, each bushing guarantees smooth tool entry, concentricity, and long tool life. It serves as an essential tooling asset for automotive manufacturing, aerospace jig building, and general mechanical workshops. Ultimately, this advanced drill bushing delivers unyielding hole accuracy, fixture longevity, and flawless production repeatability.

Serves as the primary tool-guiding insert for drill jigs and template-based manufacturing fixtures.
Prevents drill bit deflection and wandering when entering angular or tough metal surfaces.
Protects expensive fixture base plates from abrasive wear during high-volume drilling runs.
Facilitates rapid replacement of worn guide holes using renewable slip-renewable bushing setups.
Guides reamers and counterboring tools accurately to precise depth and location standards.
Tamil Nadu, IndiaThey are manufactured using high-grade bearing steel (such as AISI 52100) or carbon tool steel.
They are heat-treated and case hardened to a high rating of 60 to 64 HRC to resist tool friction wear.
A fixed bushing is pressed permanently into the jig plate, whereas a renewable bushing can be removed and replaced quickly using a lock screw when worn out.
Liner sleeves are pressed permanently into the fixture plate to house renewable bushings, allowing easy bush changing without damaging the fixture body.
Yes, the hardened steel structure is fully resistant to corrosion from standard water-soluble coolants and cutting oils.
