Spot-Drilling Guidance
- Point-Angle Selection: Match 60°, 90° or 120° to the spot, chamfer and following-drill requirements.
- Shallow Operation: Use the tool primarily for spotting and selected light chamfering, not deep-hole drilling.
- Rigid Setup: Minimize runout and overhang to maintain spot location and edge stability.
- Parameter Confirmation: Adjust speed, feed and coolant to the exact workpiece grade and hardness.

Pertanyaan Umum tentang Produk
Product-specific information about spotting applications, the Ø6 mm configuration, HRC65 machining capability, point geometry and operating requirements for this solid carbide spot drill.
What is this Ø6 mm solid carbide spot drill used for?
This spot drill is designed to create an accurate starting position before drilling with a twist drill. Its short, rigid construction helps reduce drill walking and supports more consistent hole location during CNC machining.
Can this spot drill be used for chamfering?
It can be used for selected light chamfering or countersinking operations when the point angle and required chamfer geometry are compatible. The final chamfer diameter, depth and included angle should be confirmed before machining.
Why does this spot drill use a 2-flute geometry?
The 2-flute geometry provides balanced cutting forces, cutting-edge support and chip space. This configuration helps maintain centering stability and consistent spot geometry during CNC positioning operations.
What does HRC65 mean for this spot drill?
HRC65 indicates the upper application target for selected hardened materials under suitable machining conditions. It does not mean that every workpiece at 65 HRC can be machined with the same parameters. The material grade, heat treatment, spotting depth, coating and machine rigidity must be confirmed.
Which materials can this spot drill machine?
It can be configured for carbon steel, alloy steel, tool steel, mold steel and selected pre-hardened or hardened materials. Final suitability depends on the exact workpiece grade, hardness, coating and machining conditions.
Should the spot-drill angle match the following twist drill?
For conventional spotting, the spot-drill angle is generally selected so the following twist drill contacts near its point before its outer cutting corners. The correct angle depends on the following drill geometry and the required spotting or chamfering result.
Can this spot drill be used for full-depth hole drilling?
No. A spot drill is intended primarily for shallow spotting, positioning and selected chamfering operations. Full-depth holes should be machined with a twist drill or another drill designed for the required hole depth and chip evacuation.
Informasi apa saja yang diperlukan untuk mendapatkan penawaran harga?
Please provide the Ø6 mm cutting diameter requirement, point angle, workpiece material, actual hardness, spotting or chamfering depth, coating preference and estimated quantity. A drawing is recommended when the spot geometry or dimensions are non-standard.
Pertanyaan Umum (FAQ) tentang Pemesanan & OEM
General information for trial orders, custom point angles, private labeling and production scheduling.
Do you accept small trial orders?
Yes. Small sample or trial orders are welcomed for evaluating positioning accuracy, spot quality, cutting-edge stability and tool life before committing to volume purchasing.
Can other diameters and point angles be ordered?
Yes. In addition to the Ø6 mm configuration, other cutting diameters, point angles, flute lengths, overall lengths and shank dimensions can be reviewed according to the application or customer drawing.
Can the carbide grade and coating be customized?
Yes. The carbide grade, cutting-edge preparation and coating can be reviewed according to the workpiece material, hardness, cutting temperature and required tool life.
Is OEM laser marking available?
Yes. Custom shank laser marking such as logo, model number, diameter, point angle or batch identification can be reviewed together with OEM labels, individual tool protection and branded packaging requirements.
What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom point angles, special coatings and OEM orders require additional production time. The exact schedule is confirmed according to specification, quantity, coating and current production capacity.
