12D 14mm Solid Carbide Deep Hole Drills for SC45 304 steel TiSiN Coating

12D 14mm Solid Carbide Deep Hole Drills for 45# 304 steel TiSiN Coating

Introduction:

High-performance 12×D (168mm depth) solid carbide deep hole drills designed for precision drilling in 45# carbon steel and 304 stainless steel. Features TiSiN coating for enhanced wear resistance and extended tool life.

Specification:

Features:

✅ Ultra-Fine Grain Carbide Substrate – Optimized for high rigidity and fracture resistance in deep hole drilling.

✅ TiSiN Coating – Superior heat resistance (up to 1100°C), reducing crater wear and adhesion.

✅ 12×D Deep Hole Capability – Stable drilling up to 168mm depth (14mm diameter).

✅ Internal Coolant Channels – High-pressure coolant (5–15 MPa) for efficient chip evacuation.

✅ Optimized Geometry – Split-point design reduces thrust force and improves hole straightness.

Applications:

• • Hydraulic Components – Valve blocks, cylinder rods

  • Oil & Gas Equipment – Drill collars, manifolds

  • Mold & Die – Ejection pin holes, cooling channels

  • General Machining – Long-hole components in steel/stainless
