Ingersoll Rand NS11-B22-19 Beryllium Copper Replacement Needle | 5" Length | Set of 19

When replacing worn scaler needles or selecting an alternative needle material for metal surface cleaning, the Ingersoll Rand NS11-B22-19 Beryllium Copper Replacement Needle Set provides a manufacturer-listed option for compatible pneumatic needle scaler attachments. This set contains 19 beryllium copper needles, each measuring 5 inches (127 mm) long with a 3 mm nominal diameter. The beryllium copper construction distinguishes this set from standard steel needles and is commonly selected for applications where reduced spark generation is a consideration. The individual needles move against uneven surfaces during scaler operation, helping remove loose deposits from weld profiles, curved components, and textured metalwork.

Ingersoll Rand identifies NS11-B22-19 as an optional replacement needle set in its Construction Tool Steels and Accessories catalog. The set corresponds to the beryllium copper needle configuration used with the NS11BB rectangular needle housing; the manufacturer's needle scaler parts documentation also identifies it for the NS11AB round housing attachment. The needles are intended to replace worn or damaged components while retaining an otherwise serviceable compatible housing. This product includes replacement needles only, not the needle housing or pneumatic scaler. Although beryllium copper is associated with reduced-sparking applications, suitability for a particular hazardous environment must be established through the applicable safety requirements and equipment documentation.

FAQs:

• Q: How many needles are included in the Ingersoll Rand NS11-B22-19 set?

  A: The manufacturer's catalog specifies 19 beryllium copper replacement needles. Each needle measures 5 inches (127 mm) long and has a nominal diameter of 3 mm.

• Q: Which needle housings use the NS11-B22-19 replacement set?

  A: Ingersoll Rand identifies this needle set for beryllium copper attachments, including the NS11BB rectangular housing and NS11AB round housing listed in its parts documentation. Confirm the existing housing part number before ordering.

• Q: What is the difference between NS11-B22-19 and NS11-22-19?

  A: Both are 19-piece replacement sets with 5-inch needles and a 3 mm nominal diameter. NS11-B22-19 uses beryllium copper, while NS11-22-19 contains standard steel needles. The two materials are listed separately to support different application requirements.

• Q: Are these needles non-sparking?

  A: Beryllium copper needles are commonly classified as reduced-sparking or non-sparking products, but that terminology does not mean sparks are impossible. The referenced Ingersoll Rand catalog confirms the material but does not provide an explosion-protection certification or guarantee suitability for hazardous atmospheres. Evaluate the complete tool, workpiece, and working environment before use.

• Q: Does this set include a pneumatic scaler or needle housing?

  A: No. NS11-B22-19 consists of replacement needles only. The needle housing and pneumatic scaler must be obtained separately if required.

• Q: Can beryllium copper needles be sharpened or modified?

  A: Do not grind, sharpen, or modify these needles without a manufacturer-approved procedure. Machining or abrading beryllium-containing alloys can produce hazardous airborne particles. Replace damaged or excessively worn needles according to the manufacturer's maintenance instructions.
