Outstanding Performance of Drills : Effect of NexGen Edge Preparation
…An AXIS mICRO Tools Perspective
One of the differentiations that high performance tools have is the preparation of their cutting edge. Cutting edge preparation influences the Thermo-Mechanic aspects of the cutting process such as the deformation zone, the temperature distribution in the cutting process, the machining process, the chip formation and its flow, the superficial integrity of the job, resistance to wear and microchipping and tool life.
Cutting edge preparation is the process of adapting the surface of the cutting edge for improving the contact zone for machining and the coating process. The cutting-edge preparation could be done by either honing, chamfering or the combination of both to improve the microtopography for efficient and effective cutting action.
When the process is executed properly it increases the strength of the cutting edge and lifetime of the tool, increases coating productivity, minimizes the possibility of built-up-edge formation and enhances surface quality of the job.
AXIS mICRO Tools uses a unique proprietary superfinishing process to stabilize the cutting edges.The process is highly reliable, consistent and repeatable. Application industries benefiting from this process are Aerospace, Medical, mICRO mACHINING, e Mobility, Consumer Electronics, to name a few and the list is increasing.
Here is a case study which brings succinctly the benefits of superfinishing and edge preparation on the performance of AXIS Tools used in a high precision application in Aerospace Industry.
Case Study : Machining of Engine Case
Cases are an integral part of the Aircraft Engine that shield and support the parts required for combustion. Hence, they are made from materials that can withstand rapid changes in temperature and are light weighted as well. Heat Resistant Super Alloys (HRSA) such as Inconel and Nickel Alloys, Titanium and Stainless Steels are the materials of choice in such applications.
Drilling Nickel based super alloy is very challenging due to the material properties, operating conditions – large amount of heat generation and its dissipation – and the high component quality requirements.
Here is a case of effective design, appropriate edge preparation, and superfinishing – to enhance coating productivity and chip evacuation
( heat dissipation ) – that has resulted in the outstanding performance of the drill.
Enhanced Tool Performance

Distinguishing Features of the Drill in use
Conclusion Controlled and Consistent micro honing of the cutting edge with a satisfactory texture for subsequent coating process results in strengthening of the cutting edge for improved cutting action, better component quality and extended tool life.

Micro-Drilling with AXIS mICRO Drills
Ultra mICRO and mICRO Drills manufacturer in India is AXIS Tools. Generally creation of very small holes 0.5 millimeters or less is defined as Micro Drilling. Micro-drilling is growing at fast pace as parts and systems are miniaturized and new products are created, especially in the electronics, medical and micro-mechanical.
Many large workpieces also require ultra small holes. This process is significantly different to conventional drilling not only in the size of the holes, but in the methods used to drill them.
Micro holes generally have extreme tight tolerances for depth, diameter, straightness and hole wall finish.
Breaking through the threshold of >3.00 mm diameter means that machining get much more precise needing disciplined drill room to make it work well.
Micro-drilling requires very controlled work environment and tight process control.
Drilling machines that have very high sensitivity and fine resolution in the feed axis. Machines must also have very precise spindles capable of high – speed rotation with low dynamic runout <0.003mmm or lower.
Specialised machines have been developed specifically to perform
micro-drilling /micro-machining operations.
About Ultra mICRO and mICRO Drills manufacturer in India
Generally Micro-drills have common shank with shanks ranging from ~3 / 3.175mm /4mm diameter(sometimes 1.00/1.50/2.00 ) shank sizes and Overall lengths ranging from 25/30/32/35/38/40/45/50 mm
Tools should be held in Ultra Precision collets .
Key to efficient micro-drilling is the drill’s ability to produce even wear across all cutting edges in order to reduce cutting forces required for chips evacuation and prevent chips from welding themselves to the flutes. Therefore, the surface finish on these drills must be ultra fine.
Matching the material to be drilled to the cutting tool is similar to conventional drilling operations except that in micro-drilling, the cutting edges must be very sharp and dead on center. Micro-drills do not have structural integrity to punch/bull their way through a workpiece.
Micro-drill makers influence the performance of tools in different materials by varying the geometry of the drill, tool materials and Coatings.
Once the process basics for micro-drilling are in place, feed control, spindle and toolholder runout; cutter material and geometry; and cut data—micro boring and reaming to hold <3 microns tolerances are reachable.
Deep hole Drilling
Deep hole drilling with micro-tools is improving as the cutting tools machines and techniques improve.
Possibilities range from l/d of 10 /15 which are standard to even 30/40 are possible under certain application conditions and materials with peck-drilling.
Center drills with a reverse diameter tolerance (i.e. +0.004 mm/ -0) rather than the standard tolerance in the opposite (negative) direction provide a pilot hole for deep drilling operations. This operation allows the long and structurally weak drill to enter a slightly oversize hole to prevent bending and breakage.
Thru Coolant drills are available from 1.00mm and even down to 0.50mm drill dia from AXIS and few high end manufacturers.
Micro-drilling can be used very effectively in volume production both in workpiece quantities and number of holes per part with quality Micro-drills.
mICRO Drills smaller than a human hair
Handling Micro-drills that are smaller than a human hair requires not only new machining process considerations, but understanding the need for gentle handling of these fragile cutters. Using micro-drills is learnable skill which comes with experience. This has achieved excellence in producing High Precision mICRO Tools for Precision.

angle, sharp cutting edges and polished flutes.
Graphite / Green Stage Ceramic Machining
As graphite is abrasive and brittle in nature, resulting into difficult machining. Graphite Electrodes used in EDM need to be precise and accurate. AXIS offers tmicro-drills with close tolerances and highly uniform CVD Diamond Coating resulting into high quality and precise machining of graphite electrodes and green stage ceramics.
Hardened Steels
During the machining of Hard parts Tools wear is very fast because of high heat generated during machining. Its machining requires special edge stabalisation treatment on cutting edges along with strongly adhesent coating which can reduce heat
generation during machining. Our In-house smooth Coatings and special capability to ensure controlled edge stabilisation adds an additional feature to AXIS micro-drills to meet exacting application needs.
