Stens 80 Grit Lapping Compound (25 lb Bucket)
Best for: Clubs, small shops, or households with frequent reel maintenance and larger blade populations. The 25 lb bucket provides long-term supply for repeated back-lapping sessions.

Buying Guide
Key factors to consider when selecting an 80 grit lapping compound for reel mowers include grit consistency, premixed versus DIY mixing, packaging size, and compatibility with your mower model. Below are practical questions and answers to guide your choice.
What size is right for my mowing routine?
For occasional maintenance on a single mower, 7 oz or 5 lb formats are often sufficient. If you service multiple reels or perform frequent maintenance, consider larger sizes like 24 oz or 25 lb buckets to reduce replacement frequency.
Should I choose premixed or need-to-mix formulas?
Premixed formulas save time and reduce mixing errors. They are ideal for quick touchups and home use. DIY mixes offer control over viscosity and abrasiveness but require more setup and care.
Is two-stage sharpening better than single-stage?
Two-stage options with 80 grit followed by a finer grit (such as 120) allow for initial aggressive edge restoration and subsequent smoothing. This can produce a more even cut and longer blade life, especially on heavily worn reels.
What safety considerations matter?
Wear eye protection and gloves during sharpening. Work on a stable surface, and clean blades after use to prevent residue buildup. Keep abrasives sealed when not in use to preserve consistency.
Are there additive features to look for?
Some formulas include lubricants to dissipate heat and rust inhibitors to reduce corrosion. For environments with humidity, these additives help maintain blade quality and tool longevity.
Useful tips for best results
- Apply backing pressure evenly to avoid creating dips or uneven edges.
- Rinse blades thoroughly after sharpening to remove residual compound.
- Test edge sharpness on a scrap piece of metal or non-critical blade before full use.
