Crown Drill Bit Cold Sword Tooth Drill Inside The Shank Blade Shovel Drill Deep Hole Drill

The Indexable Crown Deep‑Hole Drill features a replaceable carbide insert head with a saw‑tooth cutting edge (“saber‑tooth”) for aggressive material removal and extended wear life.
Its solid 40Cr steel body is heat‑treated and for maximum toughness, and the double‑flute geometry controls chip flow even in deep‑hole operations.
Available in diameters 10 mm–25.8 mm, it’s ideal for concrete, masonry, stone, and ferrous/non‑ferrous metals in demanding industrial applications.

Key Features

• Saw‑Tooth Carbide Inserts (Indexable): Ultra‑hard tungsten‑carbide tips formulated for rapid stock removal and long wear life.

• Double‑Flute Body: Optimized flute geometry reduces cutting forces and channels chips efficiently, even at extended lengths.

• Modular Head Design: Quick‑change insert heads and standard straight shanks (metric and imperial) allow fast maintenance and tool changeovers.

• Simple Drill Tip Replacement System: Reduces downtime and improves on-site operability.

• Made of dedicated PVD material: Compared with the hardened drill bit that requires regrinding, this drill bit has a longer tool life

Specifications

Applications

• Deep‑Hole Drilling: Efficient holes in cast iron, steels, stainless steels, and high‑temp alloys using HP deep drills.

• Concrete & Masonry: Shovel‑bit crown drills for reinforced concrete, brick, and stone installation tasks.

• Cemented Carbide Work: Precision holes in ceramic composites and non‑ferrous materials with minimal chipping.

Usage & Maintenance Tips

1. Feed Rates: Follow manufacturer‑recommended feed per revolution (e.g., 0.1 – 0.2 mm/rev) to balance tool life and surface finish.

1. Insert Indexing: Rotate or replace inserts when wear flat exceeds 0.2 mm to maintain hole accuracy.

2. Tool Cleaning: Flush internal coolant passages after each use to prevent clogging and ensure consistent coolant flow.
