Product description

TiStorm TM3 — solid carbide flat-bottom drill

Solid carbide · TiSiN · internal coolant · workpiece hardness up to 55 HRC

TiStorm TM3 is a solid carbide drill with a flat point and internal coolant channels. It is intended for drilling and axial counterboring, including entry or exit through inclined or curved surfaces. Select the size by cutting diameter, flute length, shank diameter and overall length.

1. Construction and technical specifications

The tool has a solid carbide body, a TiSiN coating and a cylindrical shank. Its flat point with a nominal included angle of 180° distinguishes it from a conventional pointed drill. Coolant outlets are located at the cutting end.

Specification	Design
Tool type	Solid carbide flat-bottom drill, TiStorm TM3 series
Tool substrate	Solid carbide — VHM
Coating	TiSiN
Point geometry	Nominal 180° included angle; designed to produce a substantially flat hole bottom
Shank	Cylindrical; diameter specified separately for the selected size
Coolant supply	Internal — through channels in the tool
Workpiece hardness	Up to 55 HRC

The 55 HRC figure refers to the hardness range of the workpiece. It is neither the hardness of the carbide tool itself nor the coating thickness. VHM and TiSiN identify the tool substrate and coating respectively.

2. Workpiece materials

Applications cover steels, including alloy and tool steels, stainless steel, cast iron and aluminium. Selection for a specific job takes account of the workpiece grade and hardness, the hole geometry and the coolant supply.

Workpiece group	Application
Steel	Drilling and axial counterboring
Alloy and tool steels	Drilling and hole-bottom machining within the hardness range up to 55 HRC
Stainless steel	Drilling and axial counterboring
Cast iron	Producing holes and counterbores
Aluminium	Producing holes and counterbores

These applications do not imply common spindle speeds and feed rates across the entire series. Cutting data must be selected for the diameter, workpiece grade and operating conditions.

3. Flat point and applications

The point geometry is designed to produce holes and counterbores with a substantially flat bottom. A slight concavity may remain due to the cutting-edge geometry; the term “flat bottom” does not specify a flatness tolerance.

Operation	Example application
Entry through an inclined or curved surface	Drilling a workpiece with a non-flat entry surface
Exit through an inclined or curved surface	Through holes emerging on a non-flat surface
Axial counterboring	Producing counterbores, including locations with restricted access and curved surfaces
Cross holes and thin sheet	Drilling through an existing transverse hole or through a thin wall
Guide holes and correction of eccentric holes	Axial operations using an appropriate machining process
Partially open holes	Drilling near a workpiece edge where part of the hole circumference remains open

For non-flat surfaces, the recommended range is up to three cutting diameters (3D). This is an application guideline, not a common flute length for every size. Check the selected variant for its exact dimensions.

The tool operates with an axial feed. It is not intended for side milling or cutting with a transverse feed. Suitability for thin walls or intersecting holes does not guarantee a completely burr-free result.

4. Internal coolant

In this version, coolant is delivered through the tool to outlets near the cutting edges. The circular close-up on each card shows the point and coolant channels, helping identify the internal-coolant design.

Before selection, check that the machine and toolholder can supply coolant through the drill shank. Matching the shank diameter alone does not confirm a functioning internal coolant path. Pressure and flow need to suit the operation; this listing does not assign one value to all diameters.

5. Reading the size designation

The variant name lists four dimensions in sequence. All values are in millimetres. The letter D in the third part identifies the shank, while the final letter L identifies overall length.

Position in the designation	Meaning
First value, preceded by Ø	Cutting diameter
Second value	Flute length — the fluted cutting portion
Third value, next to D	Cylindrical shank diameter — used to select the toolholding size
Final value, next to L	Overall drill length

The shank can be larger than the cutting diameter. Do not select the toolholder using only the first number in the designation. Flute length and overall length are also separate dimensions; neither should be measured from the photograph.

6. Sizes and selection

Dimension	Series range
Cutting diameter	Ø3–14 mm
Flute length	15–60 mm, depending on the selected size
Shank diameter	Ø4, Ø6, Ø8, Ø10, Ø12 or Ø14 mm — as specified by the variant designation
Overall length	55–105 mm

The complete set of dimensions is stated in the selected variant and on its card. The ranges in this table describe the product family; they do not imply that every diameter is available with every length or shank.

Match the hole diameter and depth to the workpiece grade, hardness, entry and exit geometry, and available coolant supply. Flute length describes the tool but does not, on its own, guarantee an allowable drilling depth for every operation.

For selection assistance, provide the workpiece grade and hardness, hole diameter and depth, surface geometry and toolholding diameter. This helps distinguish the cutting diameter from the shank diameter when choosing the tool.

7. Scope of supply and photographs

The sale unit is one TiStorm TM3 drill in the selected size. It has an integral carbide cutting portion and is not an indexable-insert drill body.

The cards use a shared illustrative photograph of this product family, with values assigned to the individual variant. The full-tool image and coolant close-up show the construction; photographic proportions are not intended for measuring length. Use the variant designation and labelled values to select the size.

8. Frequently asked questions

Can this drill be used for side milling?

No. TiStorm TM3 is intended for axial-feed operations. Its flat point does not make it suitable for use as an end mill with a transverse feed.

Will it produce a perfectly flat bottom?

The geometry produces a substantially flat bottom that may retain slight concavity. If the workpiece drawing specifies a particular flatness tolerance or bottom finish, account for that requirement when selecting the machining process.

Does 55 HRC describe the drill hardness?

No. It refers to the hardness range of the workpiece. The drill is made from solid carbide and has a TiSiN coating.

Does every size have internal coolant channels?

Yes. The variants in this listing are the internal-coolant version. To use this feature, coolant must be supplied through the machine and suitable toolholding equipment.
