GARANT Master Steel range – experts for drilling steel
The GARANT Master Steel family is characterised by particularly high process reliability and performance for drilling applications. The series offers the optimum drill for every machining task in steel – both generalists and specialists for deep hole drilling or micro drilling, making it possible to master even these particular applications with ease.
The GARANT Master Steel solid carbide drill bits:
GARANT Master Steel HPC drill
Masterful performance in steel
The latest technology meets the tried-and-tested sturdiness and reliability of a convex cutting edge. The unique combination of drill point geometry and TiAlN special coating was developed specifically to meet the requirements of steel. This permits the efficient machining of steel with maximum precision.
The solid drill body ensures higher feed rates without compromising on tool life. The convex cutting edges guarantee maximum robustness, even when processing steel with a tensile strength up to 1400 N – a key advantage for demanding applications. The special cone shape improves the stability of the cutting edge to allow precise drilling and clean cutting. And the optimised flute geometry ensures reliable chip evacuation.
The portfolio:
- Diameter range: 3mm* to 20mm
- Types:
- 4×D without through-coolant (12 2470)
- 4×D with through-coolant (12 2475)
- 6×D with through-coolant (12 2761)
- Convenient tool upgrade as the dimensions and list price are the same as the old tool.
*Use the GARANT Master Steel MICRO solid carbide micro-drill for the efficient machining of steel in diameters ranging from 0.8 mm to 3 mm.
GARANT Master Steel Feed
Absolute power: GARANT Master Steel Feed is setting standards for feed performance and tool life
With its three cutting edges, the GARANT Master Steel Feed high feed rate drill has clear advantages in applications requiring maximum performance.

3. Specially developed chisel point
- Outstanding self-centring, enabling easy spot drilling even on critical and irregular surfaces
4. Coating
- Multi-layer PVD coating with nanolayer structure for even, controlled wear behaviour and long tool life
5. Solid carbide substrate
- Greatly improved bending strength and hardness properties
6. Three guide chamfers
- Stable guidance in the bore and at the drill exit
- Exact roundness and compliance with bore tolerance
GARANT Master Steel Speed
Extreme speed for maximum efficiency: GARANT Master Steel Speed defines cutting speed
The GARANT Master Steel Speed high-speed drill is more than just another high-performance tool. Thanks to new features and its design for maximum speed, the high-end drill achieves a previously unattained metal removal rate. You will achieve maximum efficiency when processing steel on machines with low spindle power but high speed and for components with thin cross-sections. An innovative new carbide substrate. The special arrangement of the four guide chamfers and a first-rate coating enable extreme cutting speeds and great durability.
Ideal for machines with high speed and low power consumption. The GARANT Master Steel can be used with and without through-coolant (Art. No. 12 2415). Due to its low cutting forces, it is suitable for thin and unstable components. For diameters ranging from 2 mm to 20 mm.
1. Low front middle position of the main cutting edge
- Cutting forces significantly reduced during drilling
- Outstanding drilling performance even at high cutting speeds
2. Slim chisel point
- Perfect self-centring upon drill entry
- The material is cut virtually to the middle and not displaced as in the usual chisel point design
3. Coating
- Wear resistance, even at high process temperatures
4. Special guide chamfers
- Reliable tool guidance as the second guide chamfer supports the drill at an early stage
- This ensures maximum straightness and quality in terms of the hole diameter
5. Optimised solid carbide substrate
- Extreme hardness, specifically to withstand very tough conditions
6. Polished flutes
- For the highest demands regarding the bore surface quality
- Optimum chip flow at high machining volume
GARANT Master Steel Deep
Innovation meets perfection: GARANT Master Steel Deep is the ideal solution for deep hole drilling

GARANT Master Steel Micro
High-performance micro drill bits for universal material use with a focus on steel processing
The sophisticated overall system of this micro solid carbide drill guarantees maximum process reliability thanks to exactly matched tools and a expanded guide chamfer. Even holes with the smallest diameters can be drilled reliably to their maximum depth – after a precise, upstream pilot hole, e.g. with the GARANT Master Steel Micro stepped drill.
The micro drill offers an optimal compromise between core diameter and flute size, which enables efficient chip evacuation – even with long-chipping materials. The increased chip volumes and extended tool life ensure a particularly economical drilling process, even in demanding applications with the smallest drilling diameters and a high length-to-diameter ratio (L/D ratio).
- Maximum process reliability thanks to harmonised tool system and extended guide chamfer
- Precision drilling of the smallest diameters up to the maximum depth after pilot drilling
- Optimised geometry for ideal chip removal - even in difficult materials
- High economic efficiency thanks to increased metal removal rates and long tool life
- Reliable with a large L/D ratio even with the smallest drilling diameters
