Scope & Applicability

• Specifies dimensions, tolerances, and marking requirements for wooden handles used with rasps, engineers' files, and scrapers.
• Definitions per IS 707:1976 (timber technology) and IS 620:1985 (wooden tool handles) apply.
• Handles must conform to dimensions and tolerances in Table 1 (Clause 6.1).

Key Specifications from Table 1 (Dimensions in mm)

Marking (Clause 8.1)

• Must include manufacturer source, year of manufacture, and size of tool the handle fits.

Related Standards

• IS 620:1985 (Wooden Tool Handles)

This standard ensures ergonomic, durable, and standardized wooden handles for precise tool fitting.

IS 2895 Key References & Specifications

• Handles Dimensions & Tolerances (Clause 6.1, Table 1):
  Dimensions (mm) for wooden handles for rasps, engineers' files, and scrapers vary by tool size. Key dimensions include length (L), widths (A, A1), thicknesses (B, C, C1), and other features (D, E, F, G, H) with specified tolerances (±2 to ±3 mm, some with asymmetric tolerance).

• Marking Requirements (Clause 8.1):
  Each handle must be legibly marked with:

  • Manufacturer's source
  • Year of manufacture
  • Size of tool (rasp/file/scraper) it fits

• Relevant Indian Standards (Clause 2.1):

  • IS 620:1985 — Wooden tool handles general requirements
