Drilling into solid – Precision drills in solid carbide and with indexable inserts
With our tools for drilling into solid material, you achieve precise, process-reliable holes in steel, cast iron, aluminium and many other materials – from high-volume production to demanding single-part machining. Whether high-performance solid carbide drills, indexable insert drills or fine boring tools for tight tolerances: Hermann Bilz offers a comprehensive drill portfolio and supports you with fast response times whenever you need help in a hurry.
What is meant by drilling into solid material?
Drilling into solid material means producing a hole directly from solid stock, without a pre-drilled pilot hole. The focus is on reliable chip formation, coolant supply and tool guidance to ensure:
- accurate hole diameters
- straight hole paths
- defined hole tolerances and surface qualities
Depending on diameter range, hole depth, workpiece material and machine capability, you will use either solid carbide drills or indexable insert drills. For holes with increased demands on tolerance, roundness and surface finish, fine boring tools complete the range.
Benefits of drilling into solid material with Hermann Bilz tools
With Bilz drill systems you benefit from:
- High productivity thanks to optimised cutting geometries and high feed rates
- Process-reliable holes due to guide lands and optimised coolant supply for straight hole paths
- Wide diameter range in standard, extended by special designs
- Universal use in steel, cast iron, non-ferrous metals and many other materials
- Standard tools from stock and special solutions with short lead times
- Support from our application engineering team with tool selection, cutting data and process optimisation
Drill systems for drilling into solid material at a glance
For different diameter ranges, drilling tasks and production volumes, Hermann Bilz offers three coordinated drilling concepts with several drill families:
- Drilling with indexable inserts
- Flexispeed – indexable insert drill for Ø 18–39 mm, self-centering with HSSE pilot, high feed rates and tolerances up to H11
- KSB Powerbore – indexable insert drill for Ø 39–160 mm, high toughness in the centre, large cutting widths and tight tolerances
- Drilling with solid carbide
- Precispeed – solid carbide drill programme for precise holes without pilot drilling, high form accuracy and low-burr hole exit
- Turbo-Drill – high-performance solid carbide drill for all common steel grades with maximum process reliability and productivity
- Bilz Rapid – fast-delivery solid carbide drills (Ø 5–25 mm) for steel, cast iron and aluminium, also available as step drills or with 180° flat point
- F-Drill – flat drill for inclined entry surfaces and flat-bottom holes
- Fineboring
- MicroCut – fine-adjustable system with backlash-free adjustment and 2 μm setting increments for the highest demands on accuracy and surface quality
- Preci-Cut – system for boring and finishing Ø 18–40 mm with high metal-removal rates and tight tolerances (IT7–8), combined with fast and precise diameter adjustment
Typical applications for drilling into solid
Our drill systems are used in, among others:
- Automotive: holes in engine and transmission housings, flanges, suspension and structural components
- Mechanical engineering: holes in housings, frames, flanges and machine elements
- Hydraulics / pneumatics: through and connection holes in valve and control blocks
- Powertrain and energy technology: holes in shafts, housings and connecting elements
- General plant and fixture construction: wherever solid drilling operations must be performed reliably and economically
Engineering, design & standards
For optimum design of your drilling tools we take into account:
- hole diameter, depth and position
- workpiece material and required hole quality
- machine type, spindle interface and fixturing concept
- available coolant and lubrication strategy (through-coolant, emulsion, oil)
- required tolerances, surface values and cycle times
Unsere Anwendungstechnik unterstützt Sie bei:
- selection of the appropriate system (Turbo-Drill, Bilz Rapid, KSB Powerbore, Flexispeed, fine boring tools, MicroCut)
- design of grade, coating, number of cutting edges and geometry
- recommendations for cutting data on your machine
- evaluation of process stability and tool life
The more complete your information, the faster we can provide a suitable tool recommendation.
