This manual provides essential information for the safe and effective use of the Heller Tools 293020 HSS Steel Drill Bit. These drill bits are designed for precision drilling in various materials.
Главните карактеристики вклучуваат:
- Particularly long service life and great drilling performance thanks to titanium coating.
- Split point grinding and 135° point angle for optimum centering during spot drilling.
- Manufactured in special HSS quality for a long service life.
- Precision tool as per DIN 338 RN for outstanding dimensional accuracy of the hole.
- Excellent concentricity as per DIN 1414.
Апликации: Suitable for drilling in steel, iron, castings, sheet metal, non-ferrous metals, plastics, steel and cast steel up to 1400 N/mm² strength.

Поставување и подготовка
- Безбедноста на прво место: Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection, before operating any power tools.
- Изберете го точниот бит: Choose the correct drill bit size (e.g., 9.5mm) and type for the material you intend to drill. Ensure the material is within the drill bit's application range (steel, iron, etc.).
- Безбеден работен дел: Firmly secure the material to be drilled using a vise or clamps за да се спречи движење за време на дупчењето.
- Инсталација на бит: Insert the drill bit into the chuck of your drill. Ensure the bit is fully seated and centered, then tighten the chuck securely. A loose bit can be dangerous and lead to inaccurate drilling.
- Означи ја точката за дупчење: Use a center punch to mark the exact drilling location on your workpiece. This helps prevent the drill bit from wandering at the start of the drilling process.
Упатства за работа
- Започнете полека: Begin drilling at a slow speed to allow the drill bit to properly engage the material and prevent it from skidding.
- Применувајте постојан притисок: Once the bit has started to cut, apply steady, consistent pressure. Avoid excessive force, which can overheat the bit or cause it to break.
- Одржувајте ја брзината: For optimal performance and to prevent overheating, maintain the recommended drilling speed for the specific material. Generally, harder materials require slower speeds.
- Use Cutting Fluid: When drilling metals, especially harder ones, use a suitable cutting fluid or lubricant. This reduces friction, dissipates heat, and extends the life of the drill bit.
- Чисти чипови: Periodically withdraw the drill bit from the hole to clear chips and allow coolant to reach the cutting edge. This is particularly important for deeper holes.
- Дополнете ја дупката: Continue drilling until the desired depth is reached. Reduce pressure as the drill bit is about to break through the material to prevent splintering or sudden jerking.

Одржување и складирање
- Чистење: After each use, clean the drill bits to remove any debris, metal shavings, or cutting fluid residue. Use a brush or cloth.
- Инспекција: Regularly inspect the drill bits for signs of wear, dullness, or damage. A dull bit will require more force and generate more heat, leading to poor performance and potential breakage.
- Острење: If the drill bit becomes dull, it can be professionally sharpened or sharpened using a suitable drill bit sharpener. Ensure the correct point angle (135°) is maintained.
- Подмачкување/Заштита: Apply a light coat of oil to the drill bits before storage, especially if they will not be used for an extended period. This helps prevent rust and corrosion.
- Складирање: Store drill bits in their original case or a dedicated drill bit organizer. This protects the cutting edges from damage and keeps them organized. Store in a dry environment.
Решавање проблеми
| Проблем | Можна причина | Решение |
|---|---|---|
| Drill bit not cutting / Slow cutting | Dull bit, incorrect speed, insufficient pressure, wrong bit for material. | Sharpen or replace bit, adjust drill speed, apply more consistent pressure, verify bit suitability. |
| Excessive heat / Smoke | Too high speed, insufficient cutting fluid, dull bit, chips not clearing. | Reduce speed, apply cutting fluid, sharpen bit, clear chips frequently. |
| Кршење на дупчалката | Excessive force, bit binding, workpiece not secured, incorrect angle. | Reduce force, ensure workpiece is secure, maintain proper drilling angle, clear chips. |
| Дупката не е тркалезна или не е центрирана | Bit wandering, improper centering, loose chuck. | Use center punch, ensure bit is securely tightened in chuck, start slowly. |
