High Light 11 Degree Tapered Button Bit ,Medium Hard Rock Drill Bit ,H22 Carbide Mining Drilling Tool

Product Overview

The 11-degree tapered button bit is a rock drilling tool engineered for medium-hard rock and medium-depth holes. Compared with a 7-degree taper, its steeper profile provides stronger self-locking on the drill rod, reducing the risk of bit drop while still allowing efficient penetration and reliable bit changes. It pairs with H22 hexagonal tapered drill rods on YT23, YT24 and YT28 air leg rock drills, in a full diameter range of 26-42mm.

Key Features & Advantages

  • Stronger self-locking: the 11-degree taper grips the rod more firmly than a 7-degree taper, reducing bit drop during medium-deep drilling.
  • Balanced penetration: steady feed and consistent water supply deliver reliable drilling speed in medium-hard formations.
  • Easier removal than 12-degree: releases with a moderate tap, saving time compared with steep 12-degree bits.
  • Even taper wear: uniform stress distribution slows socket and rod wear for longer service life.
  • Universal compatibility: fits standard YT23/YT24/YT28 air leg rock drills with H22 taper rods, covering 26-42mm sizes.

Applications

  • Medium-hard rock mining and tunneling
  • Quarrying in medium-hard formations
  • Anchor bolt and slope support drilling
  • Medium-depth hole drilling

Operating Notes

  • Match only with 11-degree taper drill steel; clean the taper contact surfaces before assembly.
  • Keep steady feed pressure and continuous water supply to clear cuttings.
  • For hard granite and deep holes over 5m, a 12-degree taper is recommended.
  • Reverse the rod and tap moderately to remove the bit; avoid heavy hammering.

FAQ

What is the difference between 7-degree and 11-degree taper? The 11-degree taper locks more firmly for medium-hard rock and medium-depth holes, while the 7-degree taper is easier to change and suits soft to medium rock.

Which drill rods does it fit? H22 hexagonal tapered rods with a matching 11-degree taper.
